Answer 3

To solve the equation -3.5 - (x - 7.2) = -4, you can follow these steps:

1. First, distribute the negative sign inside the parentheses: -3.5 - x + 7.2 = -4

2. Next, combine like terms on the left side of the equation: (7.2 - 3.5) - x = -4

3. Calculate the result within the parentheses: 3.7 - x = -4

4. To isolate the variable x, you can add x to both sides of the equation to move it to the left side: 3.7 - x + x = -4 + x

5. Simplify: 3.7 = -4 + x

6. Now, subtract -4 from both sides to isolate x: 3.7 + 4 = x

7. Calculate the result: 7.7 = x

So, the solution to the equation is: x = 7.7
