Explicación paso a paso:
1)
2x + 7 = -3
2x = -3 - 7
2x = -10
x = -10/2
x = -5
2)
5x + - 7 = x - - 9
5x - 7 = x + 9
5x - x = 9 + 7
4x = 16
x = 16/4
x = 4
3)
-9 + 6x = 15 + 2x
6x - 2x = 15 + 9
4x = 24
x = 24/4
x = 6
4)
5x - 1 = 9
5x = 9 + 1
5x = 10
x = 10/5
x = 2
5)
4x - 2 = 8 + 3x
4x - 3x = 8 + 2
x = 10
6)
-6 + 2x - 5 = 5x + 10 - 3
-11 + 2x = 5x + 7
2x - 5x = 7 + 11
-3x = 18
x = 18/-3
x = -6
7)
8 + 12x = 15x - 19
12x - 15x = -19 - 8
-3x = -27
x = -27/-3
x = 9
