What is the solution of the equation 11 - 4x = -9?

Question

A. 5
B. - 1/2
C. -5
D. 1/2

Answer 1

To solve the equation 11 - 4x = -9, you need to isolate the variable x.

First, subtract 11 from both sides of the equation:
11 - 11 - 4x = -9 - 11
-4x = -20

Next, divide by -4 on both sides to solve for x:
-4x / -4 = -20 / -4
x = 5

The solution is A. 5.
