Answer 1

a) 8 + 2x + 2 = 4x - 6 + 4x
2x - 4x - 4x = - 8 - 2 - 6
-6x = -16
x = -16/-6 x = 2,7

b) 4x - 4 = 3x + 15 - 6x
4x - 3x + 6x = 4 + 15
7x = 19
x = 19 / 7 x = 2,71

c) 6x + 2 = 12x - 6 + 5x
6x - 12x - 5x = -2 - 6
-11x = - 8
x = -8 / -11 x = 0,73

d) -3x + 3 = 2x + 2x + 6
-3x - 2x - 2x = -3 + 6
- x = 3
x = 3/ -1 x = -3
