To solve the equation 11 - 4x = -9, we need to isolate the variable x.
First, let's subtract 11 from both sides of the equation:
11 - 11 - 4x = -9 - 11
-4x = -20
Next, let's divide both sides of the equation by -4:
-4x/-4 = -20/-4
x = 5
Therefore, the solution to the equation 11 - 4x = -9 is x = 5.
