Explicación paso a paso:
a) x + 2 = 4 b) x - 4 = -3 c) x + 2 = 2
x = 4 - 2 x = - 3 + 4 x = 2 - 2
x = 2 x = 1 x = 0
d) x - 5 = 2 e) x + 2 = - 7 f) x - 2 = 4
x = 2 + 5 x = - 7 - 2 x = 4 + 2
x = 7 x = - 9 x = 6
a) - x + 8 = 5 b) - x - 4 = 3 c) - x - 4 = 2
- x = 5 - 8 x = 3 + 4 - x = 2 + 4
- x = -3 - x = 7 - x = 6
x = 3 x = - 7 x = - 6
d) - x - 2 = 1 e) - x + 3 = - 2 f) - x + 3 = 5
- x = 1 + 2 - x = - 2 - 3 - x = 5 - 3
- x = 3 - x = - 5 - x = 2
x = - 3 x = 5 x = - 2
