Answer 1

Ответ:

Пошаговое объяснение:

3x-16 1/5=5 2/7

3x- 81/5= 37/7

3x=37/7 + 81/5

3x=752/35       разделить обе стороны на 3

x=752/105  или x=7,16

Answer 2

X= 7.16!!!!!!!!!!!!!!

Answer 3

To solve the equation 3x - 16 1/5 = 5 2/7, you'll first want to isolate the variable x. Here's how you can do it step by step:

Step 1: Add 16 1/5 to both sides of the equation to get rid of the constant on the left side:

3x - 16 1/5 + 16 1/5 = 5 2/7 + 16 1/5

3x = 5 2/7 + 16 1/5

Step 2: Add the fractions on the right side of the equation:

5 2/7 + 16 1/5 = (5 + 16) + (2/7 + 1/5)

5 2/7 + 16 1/5 = 21 + (10/35 + 7/35)

5 2/7 + 16 1/5 = 21 + (17/35)

Step 3: Convert the mixed number on the right side to an improper fraction:

5 2/7 = (7 * 5 + 2)/7 = (35 + 2)/7 = 37/7

So, the equation becomes:

3x = 21 + 17/35

Step 4: Add 21 to 17/35 on the right side:

3x = 21 + 17/35

3x = (35 * 21/35) + 17/35

3x = (735/35) + 17/35

Step 5: Combine the fractions on the right side:

3x = (735 + 17)/35

3x = 752/35

Step 6: Simplify the fraction on the right side by dividing both the numerator and denominator by their greatest common divisor, which is 8:

(752/8) / (35/8) = 94/35

So, the solution to the equation is:

3x = 94/35

Now, divide both sides by 3 to isolate x:

3x/3 = (94/35) / 3

x = (94/35) / 3

x = (94/35) * (1/3)

x = (94/105)

So, x = 94/105 is the solution to the equation.
