2(x + 1) - 2(1 - x) = - 2x + 44(x - 1) - (2x + 7) = 3 - (x - 5) + 125x - (2x - 7) + 12 = 4x - 6 + x - 13x + 4 + 2x + 3 = 14x - 6 + x - 16x + 2x + 4 = 3x + 3 - 5x - 93(x - 2) - (2x - 1) = 04(x - 3) - 5?

2(x + 1) - 2(1 - x) = - 2x + 4 4(x - 1) - (2x + 7) = 3 - (x - 5) + 12 5x - (2x - 7) + 12 = 4x - 6 + x - 1 3x + 4 + 2x + 3 = 14x - 6 + x - 1 6x + 2x + 4 = 3x + 3 - 5x - 9 3(x - 2) - (2x - 1) = 0 4(x - 3) - 5(x + 8 = 6(x + 3) - 2 3(2x - 5) - 2(5x + 4) = 7(2x1) - (3x + 1) 4(5x - 3) - 4(5x - 7) = 2x - 1 Doy 40puntos si las resuelven con procedimiento.
