Answer:
7y - 3 / x
Explanation:
So , first you have to Simplify y/x
( 0 - 3/x ) + ( 7 • y/x )
Then simplify 3/x
( 0 - 3/x ) + 7y/x
Then add the fractions which have a common denominator
(Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible)
-3 + 7y/x = 7y - 3/x
you'll get your answer as : 7y-3 / x
