1. 2x - 12 = 6x - 2
2x - 12 - 6x = -2
2x - 6x = -2 + 12
-4x = -2 + 12
-4x = 10
x = - 5 / 2
2. 7x - 3 = 2x + 9
7x - 3 - 2x = 9
7x - 2x = 9 + 3
5x = 9 + 3
5x = 12
x = 12 / 5
3. 9x + 4 - 11x = 8 + 6x - 5
-2x + 4 = 8 + 6x - 5
-2x + 4 = 3 + 6x
-2x + 4 - 6x = 3
-2x - 6x = 3 - 4
-8x = 3 - 4
-8x = -1
x = 1 / 8
4. 8x = 3 + 5x
8x + 5x = 3
13x = 3
x = 3 / 13
Espero que este bien, lo hice super rapido
