Explicación paso a paso:
1. 3x - 1 = 5x + 25
3x - 5x = 25 + 1
-2x = 26
x = 26/ -2
x = -13
2. 5x+15= 3x-20
5x - 3x = -20 -15
2x = -35
x = -35/2
3. 10x-25= 30-4x+70
10x - 25 = 100 - 4x
10x + 4x = 100 + 25
14x = 125
x = 125/14
4. 5x+6x-10=2x-5+15
11x - 10 = 2x + 10
11x - 2x = 10 + 10
9x = 20
x = 20/9
5. 5x -3 + 2 = 4x + 5 - 3x +2x
5x - 1 = 3x + 5
5x - 3x = 5 + 1
2x = 6
x = 6/2
x = 3
6. 35x + x + 25 +-2 = 5x - 2x + 20
36x + 23 = 3x + 20
36x - 3x = 20 - 23
33x = -3
x = -3/33
x = -1/11
