Resolver.

X - 2 = - 3x - 8

x + 3x = - 8 + 2

4x = - 6

x = - 6 / 4 Simplificas sacas mitad

x = - 3 / 2

x + (x - 1) - 7 = 6

x + x - 1 - 7 = 6

2x - 8 = 6

2x = 6 + 8

2x = 14

x = 14 / 2

x = 7

(9x + 6) : 3 + 2 = 13

(9x + 6) : 3 = 13 - 2

(9x + 6) : 3 = 11

9x + 6 = 11 * 3

9x + 6 = 33

9x = 33 - 6

9x = 27

x = 27 / 9

x = 3.
