To find the solution of the equation 11 - 4x = -9, we need to isolate the variable x.

First, we can simplify the equation by adding 9 to both sides:

11 - 4x + 9 = -9 + 9

This simplifies to:

20 - 4x = 0

Next, we can isolate the variable x by subtracting 20 from both sides:

20 - 20 - 4x = 0 - 20

This simplifies to:

-4x = -20

Finally, we can solve for x by dividing both sides by -4:

(-4x)/(-4) = (-20)/(-4)

This simplifies to:

x = 5

Therefore, the solution to the equation 11 - 4x = -9 is x = 5.

The answer is B. 5.
