Resolver.
3x - 1 = 2x + 5
3x - 2x = 5 + 1
x = 6
x - 3 = 9
x = 9 + 3
x = 12
3y = 90
y = 90/3
y = 30
3x + 9 = 2x - 3
3x - 2x = - 3 - 9
x = - 12
(x + 9)/5 = 2
x + 9 = 2 * 5
x + 9 = 10
x = 10 - 9
x = 1
- 2x - 6 = - 4x + 12
- 2x + 4x = 12 + 6
2x = 18
x = 18/2
x = 9
- 10x - 2 = - 6x - 18
- 2 + 18 = - 6x + 10x
16 = 4x
16/4 = x
4 = x
3x - 1 = 2x + 5
3x - 2x = 5 + 1
x = 6
x - 3 = 9
x = 9 + 3
x = 12
3y = 90
y = 90/3
y = 30
3x + 9 = 2x - 3
3x - 2x = - 3 - 9
x = - 12
(x + 9)/5 = 2
x + 9 = 2 * 5
x + 9 = 10
x = 10 - 9
x = 1
- 2x - 6 = - 4x + 12
- 2x + 4x = 12 + 6
2x = 18
x = 18/2
x = 9
- 10x - 2 = - 6x - 18
- 2 + 18 = - 6x + 10x
16 = 4x
16/4 = x
4 = x
