Explicación paso a paso:
a) 2x + 8 = -18
2x= - 18 - 8
2x= - 26
X= - 26/2
X= - 13
b) 4x + 14 = 26
4x = 26 - 14
4x= 12
X= 12/4
X= 3
c) 3x + 5x = -34 + 10
8x= - 24
X= - 24/8
X= - 3
d) 7x + 8x + 30 = 45
15x = 45 - 30
15x= 15
X= 15/15
X= 1
e) 6x + 7 - 3x = -1 + 2x
3x + 7 = - 1 +2x
3x - 2x = - 1 - 7
X= - 8
f) 4x - 9 = 2x - 1
4x - 2x = - 1 +9
2x= 8
X= 8/2
X= 4
g) 2x - 12:(-4) = 5x + 9
3 - 9 = 5x - 2x
-6= 3x
X= - 6/3
X= -2
h) 16 + 4x = 10x - 20
16 + 20 = 10x - 4x
36 = 6x
X= 36/6
X=6
