Trey solved the equation 1/4(8x+16) = 4x, the answer he got was 8=x. Describe the error he made. Then solve the problem...PLZ HELP!!!

Answer 1

×=2 and where are the steps to show his error?

Explanation:

1.Distribute the 1/4.

2. 2x+4=4x-2x.

subtract 2x.

3.4=4x-2x

4. Add like terms

5.4=2x

6.Divide 2

2=x

Answer 2

In this case, you can multiply both sides by 4 to get rid of the 1/4 real quick.
4[1/4(8x+16=4x]
8x+16=16x
8x=16
x=2
