Paris is trying to solve the equation 3

*x*^{2}− (2*x*− 4) = 3 + 3*x*^{2}+ 1. Her work is partially recorded below. Copy her table and fill in her missing work to solve for*x*. Homework Help ✎**Left Expression****Right Expression****Explanation**3

*x*^{2}− (2*x*− 4)3 + 3

*x*^{2}+ 1Starting expressions.

3

*x*^{2}+ (−2*x*) + 43 + 3

*x*^{2}+ 1Remove 3

*x*^{2}from both sides.−2

*x*0

Divide both sides by –2.

Solve the parentheses on the left.

Remove 4 from both sides.

*x* = 0
