Find and explain the error in the solution given. (1) 2(x-4)=56 (2) 2x-8=56 (3) 2x-8+8=56-8 (4) 2x=48 (5)2x/2=48/2 (6) x=24

ANSWER

(1).

We expand bracket to get,

(2).

Next, we add the additive inverse of -8, which is 8 to both sides of the equation to get,

(3). Error:


This is where the error occurred. Instead of adding 8 on the right hand side, 8 was rather subtracted.
