Answer 2

To solve the equation for x, follow these steps:

1. Distribute the subtraction inside the parentheses: 1 3/4 - (0.7 - 2 1/2x) = 1.17 1 3/4 - 0.7 + 2 1/2x = 1.17

2. Simplify the fractions: 7/4 - 7/10 + 5/2x = 1.17

3. Find a common denominator for the fractions (in this case, 20): (7 * 5) / 20 - (7 * 2) / 20 + 10x / 20 = 1.17 35/20 - 14/20 + 10x / 20 = 1.17

4. Combine the fractions on the left side: (35 - 14 + 10x) / 20 = 1.17 (21 + 10x) / 20 = 1.17

5. Multiply both sides of the equation by 20 to eliminate the fraction: 21 + 10x = 1.17 * 20 21 + 10x = 23.4

6. Subtract 21 from both sides of the equation: 10x = 23.4 - 21 10x = 2.4

7. Divide both sides by 10 to solve for x: x = 2.4 / 10 x = 0.24

So, the value of x that satisfies the equation is 0.24.
