Answer 3

To solve the equation -2x - 20 = 7x + 43, we can follow these steps:

Step 1: Combine like terms on both sides of the equation. -2x - 20 + 2x = 7x + 43 + 2x -20 = 9x + 43

Step 2: Move the constant term to the other side of the equation. -20 - 43 = 9x + 43 - 43 -63 = 9x

Step 3: Divide both sides of the equation by the coefficient of x to isolate x. -63/9 = 9x/9 -7 = x

Therefore, the solution to the equation -2x - 20 = 7x + 43 is x = -7.
