Andre tried to solve the equation LaTeX: \frac{1}{4}\left(x+12\right)=21 4 ( x + 12 ) = 2 , but he made a mistake. In which step was his mistake? A. Rewrite the equation

LaTeX: \frac{1}{4}\left(x+12\right)=21 4 ( x + 12 ) = 2

B. subtract 12 from both sides

LaTeX: \frac{1}{4}x=-101 4 x = − 10

C. multiply both sides by 4

LaTeX: x=-40x = − 40
