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