Question

(13 9/73 - y) - 5 8/13 = 1 7/13​

Answer 1

Ответ:

5 920/949

Объяснение:

(958/73-у)-5 8/13=1 7/13

(958/73-у)-73/13=1 7/13

(958/73-у)-73/13=20/13

958/73-у-73/13=20/13

7125/949-у=20/13

-у=20/13-7125/949

-у=-5665/949

у=5665/949

у=5 920/949

Answer 2

To solve the equation (13 9/73 - y) - 5 8/13 = 1 7/13, you can follow these steps:

Step 1: Convert all the mixed numbers to improper fractions.

• 13 9/73 = (73 * 13 + 9) / 73 = (949 + 9) / 73 = 958/73
• 5 8/13 = (13 * 5 + 8) / 13 = (65 + 8) / 13 = 73/13
• 1 7/13 = (13 * 1 + 7) / 13 = (13 + 7) / 13 = 20/13

Now, the equation becomes:

(958/73 - y) - (73/13) = 20/13

Step 2: Simplify the equation by adding (73/13) to both sides of the equation to isolate the term with y:

(958/73 - y) = 20/13 + 73/13

Step 3: Add the fractions on the right-hand side:

(958/73 - y) = 93/13

Step 4: To isolate y, subtract (958/73) from both sides of the equation:

(958/73 - y) - (958/73) = (93/13) - (958/73)

Simplify the right-hand side:

-y = (93/13) - (958/73)

Step 5: Find a common denominator to subtract the fractions:

y = (93/13) * (73/73) - (958/73) * (13/13)

y = (1209/73) - (12454/73)

Step 6: Subtract the fractions:

y = (1209 - 12454) / 73

y = -11245/73

So, the solution to the equation is:

y = -11245/73

Answer 3

To solve the equation (13 9/73 - y) - 5 8/13 = 1 7/13, you can follow these steps:

Step 1: Subtract 5 8/13 from both sides of the equation to isolate the term with "y" on the left side:

(13 9/73 - y) - 5 8/13 - 5 8/13 = 1 7/13 - 5 8/13

Step 2: Calculate the right side of the equation:

1 7/13 - 5 8/13 = (20/13) - (68/13) = -48/13

So, the equation becomes:

(13 9/73 - y) - 5 8/13 = -48/13

Step 3: Now, you need to subtract 5 8/13 from 13 9/73. This involves finding a common denominator, which is 73 in this case.

(13 9/73 - 5 8/13) = (13 * 73 + 9 - 5 * 73 - 8) / 73 = (949 - 365) / 73 = 584/73 = 8 (whole number) + 0 (remainder) + 8/73

So, the left side of the equation simplifies to:

8 8/73 - y = -48/13

Step 4: Subtract 8 8/73 from both sides of the equation:

(8 8/73 - y) - 8 8/73 = -48/13 - 8 8/73

Step 5: Calculate the right side of the equation:

-48/13 - 8 8/73 is a bit complicated, and you may want to find a common denominator to subtract them. The common denominator is 949.

-48/13 = -3512/949

Now, you can subtract the two fractions:

(-3512/949) - (8 8/73) = (-3512/949) - (8 * 73 + 8/73) = (-3512/949) - (584/949)

Now, subtract the fractions:

(-3512/949) - (584/949) = (-4096/949)

So, the right side of the equation simplifies to:

-4096/949

The equation now looks like:

(8 8/73 - y) - 8 8/73 = -4096/949

Step 6: Subtract 8 8/73 from both sides of the equation:

(8 8/73 - y) - 8 8/73 - 8 8/73 = -4096/949 - 8 8/73

Step 7: Calculate the right side of the equation.

-4096/949 - 8 8/73 is a bit complicated, but you can find a common denominator of 949 and then subtract them:

-4096/949 - 8 8/73 = (-4096/949) - (8 * 73 + 8/73) = (-4096/949) - (584/949)

Now, subtract the fractions:

(-4096/949) - (584/949) = (-4680/949)

So, the right side of the equation simplifies to:

-4680/949

The equation now becomes:

(8 8/73 - y) - 8 8/73 = -4680/949

Step 8: Subtract 8 8/73 from both sides of the equation:

(8 8/73 - y) - 8 8/73 - 8 8/73 = -4680/949 - 8 8/73

Step 9: Calculate the right side of the equation.

-4680/949 - 8 8/73 is a bit complicated, but you can find a common denominator of 949 and then subtract them:

-4680/949 - 8 8/73 = (-4680/949) - (8 * 73 + 8/73) = (-4680/949) - (584/949)

Now, subtract the fractions:

(-4680/949) - (584/949) = (-5264/949)

So, the right side of the equation simplifies to:

-5264/949

The equation now becomes:

(8 8/73 - y) - 8 8/73 = -5264/949

Step 10: Subtract 8 8/73 from both sides of the equation:

(8 8/73 - y) - 8 8/73 - 8 8/73 = -5264/949 - 8 8/73

Now, you have:

(8 8/73 - y) = -5264/949 - 8 8/73

Step 11: Calculate the right side of the equation.

To subtract -5264/949 and 8 8/73, find a common denominator, which is 949 * 73. Then subtract the fractions:

-5264/949 - 8 8/73 = (-5264/949) - (8 * 949 - 8/73)

Now, subtract the fractions:

(-5264/949) - (69392/949) = -74656/949

So, the right side of the equation simplifies to:

-74656/949

The equation now becomes:

(8 8/73 - y) = -74656/949

Step 12: To solve for y, subtract 8 8/73 from both sides of the equation:

8 8/73 - y - 8 8/73 = -74656/949 - 8 8/73

Now, you have:

• y = -74656/949 - 8 8/73

Step 13: Calculate the right side of the equation.

To subtract -74656/949 and 8 8/73, find a common denominator, which is 949 * 73. Then subtract the fractions:

-74656/949 - 8 8/73 = (-74656/949) - (8 * 949 - 8/73)

Now, subtract the fractions:

(-74656/949) - (69392/949) = -144048/949

So, the right side of the equation simplifies to:

-144048/949

Now, to express this as a mixed number:

-144048/949 = -152 (whole number) + 0 (remainder) + 952/949

The equation now becomes:

• y = -152 952/949

So, the solution to the equation (13 9/73 - y) - 5 8/13 = 1 7/13 is:

y = 152 952/949
