Question

I need help solving this

Answer 1

`\cfrac{2}{3}x-\cfrac{1}{9}x+5=20\implies \cfrac{2x}{3}-\cfrac{x}{9}+5=20\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{9}}{9\left( \cfrac{2x}{3}-\cfrac{x}{9}+5 \right)=9(20)} \\\\\\ 6x-x+45=180\implies 5x+45=180\implies 5x=135 \\\\\\ x=\cfrac{135}{5}\implies x=27`
