En resumen

5 - 4x = - 3 - 4x = - 3 - 5 - 4x = - 8 x = - 8 / - 4 x = 2 . 5 - 2(x - 3) = 15 5 - 2x + 6 = 15 - 2x + 6 + 5 = 15 - 2x + 11 = 15 - 2x = 15 - 11 - 2x = 4 x = 4 / - 2 x = - 2 . 7 - 2x = 10 + 4x - 2x - 4x = 10 - 7 - 6x = 3 x = 3 / - 6 x = - 1 / 2 .

5 - 4x = - 3 - 4x = - 3 - 5 - 4x = - 8

x = - 8 / - 4

x = 2

.

5 - 2(x - 3) = 15

5 - 2x + 6 = 15 - 2x + 6 + 5 = 15 - 2x + 11 = 15 - 2x = 15 - 11 - 2x = 4

x = 4 / - 2

x = - 2

.

7 - 2x = 10 + 4x - 2x - 4x = 10 - 7 - 6x = 3

x = 3 / - 6

x = - 1 / 2

.

- 3(x + 4) = 2(x - 5) - 3x - 12 = 2x - 10 - 3x - 2x = - 10 + 12 - 5x = 2

x = - 2 / 5

.

3 + 5(x + 4) = 4(x - 2) + 3

3 + 5x + 20 = 4x - 8 + 3

5x + 20 + 3 = 4x - 5

5x + 23 = 4x - 5

5x - 4x = - 5 - 23

x = - 28.
