Answer
$x=-19$
Work Step by Step
$2.25(4x-4)=-2+10x+12 \\\\ 9x-9=10x+10 \\\\ -9=x+10 \\\\ x=-19$
We first use the distributive property on the left side of the equation and combine like terms on the right side of the equation to simplify. We then subtract by 9x on both sides. Next, we subtract by 10 on both sides to get that x=-19.
