Explicación paso a paso:
1* 8x - 8 = - 40
8x = 40 + 8
8x = 48
X = 48 / 8
X = 6
2* - x + 1 = - 7
- X = - 7 - 1
- X = - 8
3* 2x + 2 = 4
2x = 4 - 2
2x = 2
X = 2/2
X= 1
4* 2x + 8 = 16
2x = 16 - 8
2x = 8
X = 8 /2
X = 4
5* - 3x +40 = 10
3x = 10 - 40
3 x = - 30
X = - 30 / 3
X = - 10
6* - x - 8 = 0
- X = 8
7*. -9x - 35 = 10
- 9 x = 10 + 35
- 9 x = 45
X = 45 / - 9
X = - 5
8* - 4 x + 6 = 30
- 4 x = 30 - 6
- 4x = 24
X = 24 / - 4
X = - 6
9* - 8x - 18 = 30
- 8x = 30 + 18
- 8x = 48
X = 48 / - 8
