Question

x-5/x+2=2x+1/2x preciso de ajuda​

Answer 1

Espero ter ajudado.

$\frac{x-5}{x+2}=\frac{2x+1}{2x}\\\\\left(x-5\right)\cdot \:2x=\left(x+2\right)\left(2x+1\right)\\\\2x^2-10x=2x^2+5x+2\\\\2x^2-10x-\left(2x^2+5x\right)=2x^2+5x+2-\left(2x^2+5x\right)\\\\-15x=2\\\\\frac{-15x}{-15}=\frac{2}{-15}\\\\\boxed{x=-\frac{2}{15}}$
