Answer 2

х=2 1/2-1 1/7-17/28;

2 1/2-1 1/7=1  (7-2)/14=1  5/14;

1 5/14-17/28=1  (10-17)/28=( 38-17)/28=21/28=3/4.

Ответ: х=3/4.

Answer 3

To solve the equation 17/28 + x = -1, we'll first isolate the variable x on one side of the equation. Here's the step-by-step solution:

Step 1: Subtract 17/28 from both sides to move the constant term to the right side of the equation. 17/28 + x - 17/28 = -1 - 17/28

Step 2: Simplify both sides of the equation: x = -1 - 17/28

Step 3: Find a common denominator for -1 and 17/28, which is 28. x = -28/28 - 17/28

Step 4: Combine the fractions on the right side: x = (-28 - 17) / 28

Step 5: Simplify the numerator: x = -45 / 28

Now let's add 1/7 + 2 1/2:

Step 1: Convert 2 1/2 to an improper fraction. The whole number part is 2, so the numerator will be 2 * 2 + 1 = 5. The denominator remains 2. 2 1/2 = 5/2

Step 2: Find a common denominator for 1/7 and 5/2, which is 14. 1/7 + 5/2 = 2/14 + 35/14

Step 3: Combine the fractions: 1/7 + 5/2 = (2 + 35) / 14

Step 4: Simplify the numerator: 1/7 + 5/2 = 37 / 14

So, the final results are: x = -45/28 1/7 + 2 1/2 = 37/14
