Answer:
[tex]\frac{3}{5}\left(15x-20\right)=-6x+4\left(x-6\right)[/tex]
[tex]9x-12=-6x+4x-24[/tex]
[tex]9x-12=-2x-24[/tex]
[tex]9x-12+12=-2x-24+12[/tex]
[tex]9x=-2x-12[/tex]
[tex]9x+2x=-2x-12+2x[/tex]
[tex]11x=-12[/tex]
[tex]\frac{11x}{11}=\frac{-12}{11}[/tex]
[tex]x=-\frac{12}{11}[/tex] or [tex]x=-1.090[/tex]
