B. Jeff solved a similar equation below. Is Jeff's solution correct? Explain why or why not.
3x − 2 = 5(x + 2)
3x − 2 = 5x + 10
8x = 8
x = 1

Answer 1

3rd step

Answer 2

is not possible

Answer 3

3x − 2 = 5x + 10
put the terms with x on one side and constants on the other side, what should you get

Answer 4

-12 = 2x

Answer 5

yes that is right
