Math Problem Statement

If -4x + 7 = -11, then x = ?

Solution

To solve for xx in the equation:

4x+7=11-4x + 7 = -11

we'll go through the following steps:

Step 1: Isolate the term with xx

Subtract 7 from both sides of the equation to get: 4x=117-4x = -11 - 7 4x=18-4x = -18

Step 2: Solve for xx

Divide both sides by -4: x=184x = \frac{-18}{-4} x=184x = \frac{18}{4} x=4.5x = 4.5

Answer

The correct answer is: E.  4.5\boxed{E. \; 4.5}
