Question

x-3/4 - x+1/6 =-2 podem me ajudar

Answer 1

x-3/4 - x+1/6 = -2

x/4-3/4 -x/6+1/6 =-2
x/4-x/6=-2+3/4-1/6
   3x/12-2x/12= -2+3/4-1/6                                 mmc de (4,6)= 12
x/12=-2+3/4-1/6  mmc de (1,6,4)=12
x/12= 24/12+ 9/12- 2/12
x/12= 33/12- 2/12
x/12= 31/12
(x.12=12.31 )
12x=372
x=372/12
x=31
