Question

×/8 + ×/5 = 17 -×/10

Answer 1

Resposta:

$x = 40$

Explicação passo-a-passo:

$\frac{x}{8} + \frac{x}{5} = 17 - \frac{x}{10}$

$mmc = 40$

$5x + 8x = 680 - 4x$

$5x + 8x + 4x = 680$

$17x = 680 \\ x = \frac{680}{17} = 40$

Answer 2

Explicação passo-a-passo:

$\dfrac{x}{8} + \dfrac{x}{5} = 17 - \dfrac{x}{10}$

$5x + 8x = 680 - 4x$

$13x = 680 - 4x$

$13x + 4x = 640$

$17x = 680$

$x = \dfrac{680}{17}$

X=>40
