-3,5-x+7,2=-4

-3,7-x=-4

-x=-4-3,7

-x=-7,7

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 on the left side of the equation:

-3.5 - x + 7.2 = -4

2. Now, combine like terms on the left side of the equation:

(7.2 - 3.5) - x = -4

3. Calculate the result of the subtraction on the left side:

3.7 - x = -4

4. To isolate the variable x, you can add x to both sides of the equation to get it on one side:

3.7 - x + x = -4 + x

The x terms on the left side will cancel out:

3.7 = -4 + x

5. Finally, solve for x by subtracting -4 from both sides of the equation:

3.7 + 4 = x

x = 7.7

So, the solution to the equation -3.5 - (x - 7.2) = -4 is x = 7.7.
