for
, multiply the numerator and denominator by 7.
×
= 
we can leave
as it is
and for
, we cam multiply the numerator and denominator by 8
×
=
Here's the equation now:
-
+
=-92
now simlify the fractions
numerators:
-49x-5x+8x=-46x
here's the fraction now:
=-92
We can simplify the fraction by 2 so it's 
=-92
now multiply both sides by
, which is the reciprocal of
(to isolate the variable)
