Answer 2

Respuesta:

$8x = 4x - 8 \\ 8x - 4x = - 8 \\ 4x = - 8 \\ x = \frac{ - 8}{4} \\ x = - 2$

$x - 4 = - 1 \\ x = - 1 + 4 \\ x = 3$

$4x + 5 = 12 + 3x \\ 4x - 3x = 12 - 5 \\ x = 7$

$12 = 3x \\ \frac{12}{3} = x \\ 4 = x$

$- 12x = - 36 \\ x = \frac{ - 36}{ - 12} \\ x = 3$

$\frac{x}{2} = - 5 \\ 2 \times \frac{x}{2} = - 5 \times 2 \\ x = - 10$

$\frac{x}{2} = \frac{15}{6} \\ 2 \times \frac{x}{2} = \frac{15}{6} \times 2 \\ x = \frac{15}{3} \\ x = 5$

$4x + 8 + 2x = 5x - 1 \\ 6x + 8 = 5x - 1 \\ 6x - 5x = - 1 - 9 \\ x = - 10$

$8 - 5x - 4 = - 6x + 6 \\ 4 - 5x = - 6x + 6 \\ - 5x + 6x = 6 - 4 \\ x = 2$

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

$4 = 3x + 4 \\ 4 - 4 = 3x \\ 0 = 3x \\ \frac{0}{3} = x \\ 0 = x$

$7 + x + 3x = 6 + 5x \\ 7 + 4x = 6 + 5x \\ 7 - 6 = 5x - 4x \\ 1 = x$
