Andre tried to solve the equation 1/4 ( x + 12 ) = 2. What was his mistake? Explain. 1/4x = -10
x = -40

He should expand the 1/4 on the barker (x+12) then he will have 1/4x+3 = 2 then he should subtract the 3 from the 2 meaning he will be left with 1/4x = -1 and then he should multiply the left hand side and the right hand side with 4 in order to get rid from the 1/4 so the answer is x = -4

Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4
