- 6(x - 1) + 3(3 + 4x) = 10x3(3x + 1) - x + 7 = 2(x - 1)?

- 6(x - 1) + 3(3 + 4x) = 10x 3(3x + 1) - x + 7 = 2(x - 1).

En resumen

1) - 6 (x - 1) + 3 (3 + 4x) = 10x - 6x + 6 + 9 + 12x = 10x15 + 6x = 10x15 = 4x15 / 4 = x2) 3 (3x + 1) - x + 7 = 2(x - 1)9x + 3 - x + 7 = 2x - 28x + 10 = 2x - 26x = - 12X = - 2.
