-5/8x+1/4=1/8

Oct 3rd, 2015

Thank you for the opportunity to help you with your question!

-5/8x+1/4=1/8

         -1/4   -1/4      *subtract 1/4 from both sides of equation

-5/8x = 1/8 -1/4       *we need a common denominator, both 8 and 4 go into 8, so let 8 be it.

-5/8x = 1/8 -2/8       *our fraction 1/4 is now 2/8 since 4 goes into 8 twice, we multiply both top & bottom by 2

-5/8x = -1/8               *subtract the two fractions

(-8/5) (-5/8) x = (-8/5) (-1/8)     *divide both sides of eqn by -5/8, but remember, dividing by a fraction means                                                         multiplying by the reciprocal.

x= 1/5                        *everything on the left will then cancel.  On the right, the 8's cancel, and the two neg's                                          make a positive, therefore, we multiply straight across.

Hope this helps!!!  let me know if you have any further questions, or need help explaining any step here!
