Final answer:

To solve the equation -2x + 5 = 9 for x, you need to subtract 5 from both sides and then divide both sides by -2.

Step-by-step explanation:

To solve the equation -2x + 5 = 9 for x, we need to isolate the variable x on one side of the equation. In order to do that, we need to perform the addition and subtraction operations on both sides of the equation.

First, we subtract 5 from both sides to get -2x = 4. Then, we divide both sides by -2 to solve for x. The final step is to simplify the expression, which gives us x = -2.
