Answer:
[tex]-3\left(2x-9\right)=3\left(16-x\right)[/tex]
[tex]-3\left(2x-9\right)[/tex]
[tex]=-3\cdot \:2x-\left(-3\right)\cdot \:9[/tex]
[tex]-3\cdot \:2x+3\cdot \:9[/tex]
[tex]=-6x+3\cdot \:9[/tex]
[tex]=-6x+27[/tex]
[tex]3\left(16-x\right)[/tex]
[tex]=3\cdot \:16-3x[/tex]
[tex]=48-3x[/tex]
[tex]-6x+27=48-3x[/tex]
[tex]-6x+27-27=48-3x-27[/tex]
[tex]-6x=-3x+21[/tex]
[tex]-6x+3x=-3x+21+3x[/tex]
[tex]-3x=21[/tex]
[tex]\frac{-3x}{-3}=\frac{21}{-3}[/tex]
[tex]x=-7[/tex]
