$3x-9(x-2)=2(x-13)$
Expand $ -9(x-2):{\quad}-9x+18$$3x-9x+18=2(x-13)$
Add similar elements: $ 3x-9x=-6x$$-6x+18=2(x-13)$
Expand $2(x-13):{\quad}2x-26$$-6x+18=2x-26$
Subtract $18$ from both sides$-6x+18-18=2x-26-18$
Simplify$-6x=2x-44$
Subtract $2x$ from both sides$-6x-2x=2x-44-2x$
Simplify$-8x=-44$
Divide both sides by $-8$$\frac{-8x}{-8}=\frac{-44}{-8}$
Simplify$x=\frac{11}{2}$
