B) 2x = - 234 x = - 234 / 2 x = - 117

c) - 120 = 8x - 120 / 8 = x - 15 = 8

d) - 24x = - 96 24x = 96 x = 96 / 24 x = 4

e)68x = - 204 x = - 204 / 68 x = - 6

f) - 5x = - 9x - 24 - 5x + 9x = - 24 4x = - 24 x = - 24 / 4 x = - 6

g)5 + 2x = 5x - 7 5 + 7 = 5x - 2x 12 = 3x 12 / 3 = x 4 = x

h)1 + 4x - 3 = 6x + 8 - 2 + 4x = 6x + 8 - 2 - 8 = 6x - 4x - 10 = 2x - 10 / 2 = x - 5 = x

i)25x = 120 - 5x + 10x 25x = 120 + 5x 25x - 5x = 120 20x = 120 x = 120 / 20 x = 6

j)8(x - 2) = 4(x + 3) 8x - 16 = 4x + 12 8x - 4x = 12 + 16 4x = 28 x = 28 / 4 x = 7

espero qt sirva : ).
