Question

How do i solve this equation?

Answer 1

Answer: x = - 2.5

Explanation:

|11 - 4x| = 21

11 - 4x = 21

subtract 11

11- 11 - 4x = 21 -11

-4x = 10

divide by -4

-4x/-4 = 10/-4

x = -2.5

Answer 2

x = -2.5

Explanation:

The absolute value symbols just mean that if the result of what is inside the symbols is always positive.

You can treat this problem like a normal equation.

|11 - 4x| = 21

Subtract 11 from both sides

-4x = 10

Divide both sides by -4

x = -2.5
