Explicación paso a paso:
A) x + 7 = 22 E) 6x = 42
x = 22 - 7 x = 42 / 6
x = 15 x = 7
B) x + 15 = 51 F) 8x = 88 I) 5x - 5 = 2x + 16
x = 51 - 15 x = 88 / 8 5x - 2x = 16 + 5
x = 36 x = 11 3x = 21
x = 21 / 3
C) x - 19 = 40 G) x / 3 = 9 x = 7
x = 40 + 19 x = 9 . 3
x = 59 x = 27 J) 5x + 10 = 2x + 40
5x - 2x = 40 - 10
D) x - 25 = 50 H) x / 8 = 7 3x = 30
x = 50 + 25 x = 8 . 7 x = 30 / 3
x = 75 x = 56 x = 10
K) 4x - 3 = 3x + 2 L) 6x - 6 = 5x + 5
4x - 3x = 2 + 3 6x - 5x = 5 + 6
x = 5 x = 11
