$x=6$
If you have trouble following the steps below, please review the order of operations (PEMDAS) or the distributive property. Note that, because we are told that $y=0$, the expression involving $x$ is also equal to zero. $y=2[3x-(4x-6)]-5(x-6)=0$ $2(3x-4x+6)-5x+30=0$ $2(-x+6)-5x+30=0$ $-2x+12-5x+30=0$ $-7x+42=0$ $7x=42$ $x=6$
