Question

Resolver la siguiente ecuacion 7/5x - 3/8 = 2/5 + 3/4x

Answer 1

Resolución:

7/5x - 3/8 = 2/5 + 3/4x

$\frac{56}{40x}-\frac{15x}{40x}=\frac{8x}{20x}+\frac{15}{20x}$.... Homogenizando

$\frac{56-15x}{40x}=\frac{8x+15}{20x}\\\\Simplicando..\frac{56-15x}{2}=8x+15$

$56-15x=2(8x+15)\\56-15x=16x+30\\56-30=(16+15)x\\26=31x\\x=31/26..R$
