Based on the numbers given (8,56, and 7), let's make all of the denominators be 56
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)
×
=-92×
x=112
