Question

Which of the following values makes the equation

4x − 8 = −4 true?

−3

−1

1

3

Answer 1

true? I believe due to how it starts with positive 4 and is subtracted by -8 this conceding a negative number.

Answer 2

Answer: C) 1

Work Shown:

4x - 8 = -4

4x = -4+8

4x = 4

x = 4/4

x = 1

To check the answer, we replace x with 1 in the original equation. After simplifying, we should get the same thing on both sides

4x - 8 = -4

4(1) - 8 = -4

4 - 8 = -4

-4 = -4

The answer is confirmed.
