Question

resolva as equaçoes
a) 14/3x - 7/3x + 1/6x = (x - 2) b)8/9 (x - 3) + 1/9 (x - 3) = 9

Answer 1

_14x_ + _7x_ - _x_ = x - 2
    3          3        6
m.m.c ⇒ 6
28x + 14x - x = 6x - 12
35x = -12
x = - _12_
          35

_8(x - 3)_  + _(x - 3)  = 9
       9                9
8x - 24 + x - 3 =81
9x = 108
x = 108/9
x = 12
