En resumen
4(x - 1) - 5 (3 - x) = 14x - 2 (5x - 3) 4x - 4 - 15 + 5x = 14x - 10x + 6 5x + 4x - 15 - 4 = 4x + 6 9x - 19 = 4x + 6 9x - 4x = 6 + 19 5x = 25 x = 25 / 5 x = 5 .

4(x - 1) - 5 (3 - x) = 14x - 2 (5x - 3)
4x - 4 - 15 + 5x = 14x - 10x + 6
5x + 4x - 15 - 4 = 4x + 6
9x - 19 = 4x + 6
9x - 4x = 6 + 19
5x = 25
x = 25 / 5
x = 5
.
2(3x - 2) - 5x = 2 ( x - 3 ) + 9
6x - 4 - 5x = 2x - 6 + 9
6x - 5x - 4 = 2x + 3
x - 4 = 2x + 3
x - 2x = 3 + 4 - x = 7
x = - 7.
