- 5 = 7 – 3x?
- 5 = 7 – 3x . 14 = - 2 + 8x / 3 x / 3 + 2 = 5 2 / (x - 1) + 3 = 20 / (x - 1) + 2 2x / 4 + 3x = 30 - x.
- 5 = 7 – 3x . 14 = - 2 + 8x / 3 x / 3 + 2 = 5 2 / (x - 1) + 3 = 20 / (x - 1) + 2 2x / 4 + 3x = 30 - x.
En resumen
1) x = 4 2) x = 6 3) x = 1 4) x = 19 5) x = 6. 666.
1) x = 4 2) x = 6 3) x = 1 4) x = 19 5) x = 6.

- 5 = 7 - 3x
3x = 7 + 5
x = 12 / 3
x = 4
14 = - 2 + 8x / 3
8x / 3 = 14 + 2
8x = 16 * 3
x = 48 / 8
x = 6
x / 3 + 2 = 5
x / 3 = 5 - 2
x = 3 / 3
x = 1
2 / x - 1 + 3 = 20 / x - 1 + 2
20 / x - 1 - 2 / x - 1 = 3 - 2
18 / x - 1 = 1
18 = 1(x - 1)
18 + 1 = x
x = 19
2x / 4 + 3x = 30 - x
2x / 4 = 30 - x - 3x
2x / 4 = 30 - 4x
2x = (30 - 4x)4
2x = 120 - 16x
2x + 16x = 120
18x = 120
x = 120 / 18
x = 6.

espero que te sea de ayuda.
