Решите пожалуйста линейные уравнения ! 40 баллов !

1) 3 - 4x = 4x - 5

2) -1 + 2x = 1 + 3

3) 2x + 7 = -2x

4) - x - 7 = -5x

5) 2 + 8x = 3x + 9

белочка2369 1) 3 - 4x = 4x - 5
- 4x - 4x = - 5 - 3
- 8x = - 8
x = 1

2) -1 + 2x = 10х + 3
2x - 10х = 3 + 1
- 8x = 4
x = - 0,5

3) 2x + 7 = - 2x
2x + 2x = - 7
4x = - 7
x = - 1,75

4) - x - 7 = - 5x
- x + 5x = 7
4x = 7
x = 1,75

5) 2 + 8x = 3x + 9
8x - 3x = 9 - 2
5x = 7
x = 1,4
