Question

Andre tried to solve the equation 1/4(x+12)=2 what was his mistake?

Answer 1

He didn’t multiply by 4 first

Answer 2

Answer:

x = 8 (read below for Andre's mistakes)

Step-by-step explanation:

How to actually solve:

1/4(x+12) = 2

1/4(-4+12)=2

1/4(8)=2

How he solves:

1/4(x+12)=2

1/4(x+12)-12=2-12

1/4x=-10

x=-40

So apparently Andre's first mistake is he didn't use PEMDAS. His second mistake was instead of dividing by 4, he multiplied by 4.
