Gwendolyn is asked to solve the equation - 43 - 3) = 20. She sh

-4 (x - 3) = 20

- 4x + 12 = 20

- 4x = 32

x = - 8

Unfortunately, Gwendolyn's work is flawed. Explain the flaw in Gwendolyns work

-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.

Step-by-step explanation:

It should have been, write problem

-4 (x - 3) = 20

Use distributive property.

-4x + 12 = 20

subtract 12 from each side

-4x = 8

divide each side by - 4

x = - 2
