Explicación paso a paso:
E) 6x = 42
x = 42/6
x = 7
F) 8x = 88
x = 88/8
x = 11
G) x/3 = 9
x = (3)(9)
x = 27
H) x/8 = 7
x = (7)(8) = 56
x = 56
I) 5x -5 = 2x + 16
5x - 2x = 16 + 5
3x = 21
x = 21/3
J) 5x + 10 = 2x + 40
5x - 2x = 40 - 10
3x = 30
x = 30/3
x = 10
K) 4x -3 = 3x + 2
4x - 3x = 2 + 3
x = 5
L) 6x - 6 = 5x +5
6x -5x = 5 + 6
