Explicación paso a paso:
18x - 2x + 2 + 6 = 15x + 12
16x + 8 = 15x + 12
16x - 15x = 12 - 8
x = 4
7m - 5 = 5m - 13
7m - 5m = -13 + 5
2m = -8
m = -8/2
m = -4
b - 9 = 6b - 54
b - 6b = -54 + 9
-5b = -45
b = -45/-5
b = 9
18x-2x+2+6=15x +12
20x-15x=8+12
5x=20
x=20/5
x=4
7m-5=5m-13
7m-5m=13+5m
2m=18
m=18/2
m=9
b-9=6b-54
9+54=6b-b
63=5b
5/63=b
b=12.6
