2x-10=1/3(x-9) what's x?
\(2x-10=\frac{1}{3}(x-9)\\ 6x-30=x-9\\ 5x=21\\ x=\frac{21}{5}\)
\(2x-10=\frac{1}{3}(x-9)\\\\ 2x-10=\frac{1}{3}x-3\ \ \ | Add\ 10\\\\ 2x=\frac{1}{3}x+7\ \ \ | subtract \ \frac{1}{3}x\\\\ 1\frac{2}{3}x=7\\\\ \frac{5}{3}x=7\ \ \ \ | divide\ by\ \frac{5}{3}\\\\ x=7*\frac{3}{5}\\\\ \boxed{x=4,2}\)
