1) 15 + 5x = 20x + 15x
15 + 5x = 35x
15 = 35x - 5x
15 = 30x
x = 30 / 15
x = 2
2) 2 − 5 = +6
2x = x + 11
2x - x = 11
x = 11
3) 28x - 21x = 7x + 21
7x = 7x - 21
7x + 7x = 21
14x = 21
x = 21 / 14
x = 1.5
4) 4x - 2x = 20 + 8
2x = 28
x = 28 / 2
x = 14
5) 10x = 58 + 28
10x = 86
x = 86/10
x = 8.6
6) (la 6 y 7 no se perdón)
8) = 6
3x + 3 = 6
3x = 6 - 3
3x = 3
x = 3/3
x = 1
9) 4x - 8 = 2x + 8
4x - 2x = 8 + 8
2x = 16
x = 16/2
x = 8
10) 5x = 18 + 7
5x = 25
x = 25 / 5
x = 5
