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.
