Question

4x +2 = -2x -12
50 +6x = 30 -4x
5x + 12 = -2x -6

Answer 1

Explicación paso a paso:

$4x + 2 = - 2x - 12 \\ 4x + 2x = - 12 - 2 \\ 6x = - 14 \\ x = \frac{ - 14}{6} \\ x = \frac{ - 7}{3}$

$50 + 6x = 30 - 4x \\ 6x + 4x = 30 - 50 \\ 10x = - 20 \\ x = \frac{ - 20}{10} \\ x = - 2$

$5x + 12 = - 2x - 6 \\ 5x + 2x = - 6 - 12 \\ 7x = - 18 \\ x = \frac{ - 18}{7}$
