Answer 1

Respuesta:

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

$x - 8 = 2x - 6 \\ - 8 + 6 = 2x -x \\ - 2 = x$

$8x - 2 = 10x \\ - 2 = 10x - 8x \\ - 2 = 2x \\ \frac{ - 2}{2} = x \\ - 1 = x$

$2x - 1 = x - 1 \\ 2x - x = - 1 + 1 \\ x = 0$

$4x - 5 = 2x - 7 \\ 4x - 2x = - 7 + 5 \\ 2x = - 2 \\ x = \frac{ - 2}{2} \\ x = - 1$

$5x - 1 = x + 7 \\ 5x - x = 7 + 1 \\ 4x = 8 \\x = \frac{8}{4} \\ x = 2$
