Explicación paso a paso:
1) 4x - 9 = 3
4x = 9 + 3
4x = 12
x = 12/4
x = 3
2) 2x - 4 = -3x + 6
2x + 3x = 6 + 4
5x = 10
x = 10/5
x = 2
3) 3x + 5 - 2x = 3x + 8
5 - 2x = 8
-2x = 8 - 5
-2x = 3
x = -2/3
4) 4x + 3x - 2 = 8x + 4 - 6
7x - 8x = 2 + 4 - 6
-x = 0
x = 0
5) 7x - 8 = 62
7x = 62 + 8
7x = 70
x = 70/7
x = 10
