Question

a soluçao da equaçao x/3 + 1/4 =(2x-3) /5 é?​

Answer 1

Resposta:

$\frac{x}{3}+\frac{1}{4}=\frac{2x-3}{5}$

$\frac{4x}{12}+\frac{3}{12}=\frac{2x-3}{5}$

$\frac{4x+3}{12}=\frac{2x-3}{5}$

$5(4x+3)=12(2x-3)$

$20x+15=24x-36$

$20x-24x+15+36=0$

$-4x+51=0$

$-4x=-51$

$4x=51$

$x=\frac{51}{4}$
