Answer 1

Respuesta:

1)

$\frac{2x - 10}{3} + 4 = 2(x - 1)$

$\frac{2x - 10}{3} + \frac{12}{3} = 2x - 2$

$\frac{2x - 10 + 12}{3} = 2x - 2$

$2x + 2 = (2x - 2) \times 3$

$2x + 2 = 6x - 6$

$2x - 6x = - 6 - 2$

$- 4x = - 8$

$x = \frac{ - 8}{ - 4}$

$x = 2$

2)

$\frac{7x}{8} - \frac{5}{2} = x - 1$

$\frac{7x}{8} - \frac{20}{8} = x - 1$

$\frac{7x - 20}{8} = x - 1$

$7x - 20 = (x - 1) \times 8$

$7x - 20 = 8x - 8$

$7x - 8x = - 8 + 20$

$- x = 12$

$x = - 12$
