1) 2x + 5 = 18
2x = 18 - 5
2x = 13
x = 13 : 2
x = 6.5
2) 5 + 3x = 6
3x = 6 - 5
3x = 1
x = 1 : 3
x = 0.3
3) 6x - 8 = 3
6x = 3 + 8
6x = 11
x = 11 : 6
x = 1.83
4) 2x + 5 = 3
2x = 3 - 5
2x = - 2
x = - 2 : 2
x = - 1
5) 5x - 3 = 8
5x = 8 + 3
5x = 12
x = 12 : 5
x = 2.4
6) -2x = 5 + 6
-2x = 11
x = 11 : (-2)
x = 5.5
7) 2x + 5 = 22
2x = 22 - 5
2x = 17
x = 17 : 2
x = 8.5
8) 7x = 18
x = 18 : 7
x = 2.57
9) 12x = 24
x = 24 : 12
x = 2
10) 6x - 17 = 4
6x = 4 + 17
6x = 21
x = 21 : 6
x = 3.5
Espero te sirva :)
