Sagot :
1) 3x-2 = x +6
3x - x = 6 + 2
2x = 8
x = 8/2
x = 4
2) 2x -7 = 6x -2
2x -6x = -2 + 7
-4x = 5
x = 5/ -4
3) 8x -5 = 2x + 6
8x - 2x = 6 + 5
6x = 11
x = 11/ 6
3x - x = 6 + 2
2x = 8
x = 8/2
x = 4
2) 2x -7 = 6x -2
2x -6x = -2 + 7
-4x = 5
x = 5/ -4
3) 8x -5 = 2x + 6
8x - 2x = 6 + 5
6x = 11
x = 11/ 6
