Answer:
He was supposed to cross multiply the equation in the original equation. Step 2 was a wrong expression
Explanations:
The given equation is:
[tex]\frac{1}{4}(x\text{ + 12) = 2}[/tex]
Cross multiply the equation, the equation becomes:
[tex]x\text{ + 12 = 8}[/tex]
x = 8 - 12
x = -4
His mistake was in step 2, he did not properly expand the equation
The proper step was to cross multiply in step 2
