I. Determina el valor de x en las siguientes ecuaciones:


       1) 4x = 2x - 12


       2) 8x - 24 = 5x


       3) 7x + 12 = 4x - 17


       4) 3x - 25 = x - 5


       5) 5x + 13 = 10x + 12


       6) 12x - 10 = -11 + 9x


       7) 36 - 6x = 34 - 4x


       8) 10x -25 = 6x - 25


       9) 11x - 1 + 5x = 65 x - 36


       10) 4x - 13 - 5x = -12x + 9 + 8x


       11) -5 + 7x +16 + x = 11x - 3 - x


       12) 6x - 12 + 4x - 1 = -x - 7x + 12 - 3x + 5


       13) 2x - (x + 5) = 6 + (x + 1)


       14) 8 - (3x + 3) = x - (2x + 1)


       15) 4x - 2 = 7x - (x + 3) + (-x - 6)
