Question

8. The equation at the right has been incorrectly solved.

a. What error was made?
-4(6-b) = 4
-24 - 4b = 4
-4b = 28
b = -7
b. What is the correct solution?

Answer 1

The equation at the right has been incorrectly solved, the answer to this is b = -7

Answer 2

When subracting the negative 24 from the left and right side, the left will cancel and the right will equal -28 instead of positive.

The final answer would just be positive 7 instead of negative.
