Answer: y = 31
Step-by-step explanation:
y = 3x + 10
y = 3(7) + 10 Plug in the 7 for x, because it shows x = 7 in the question.
y = 21 + 10
y = 31
The answer is 3 because when you give the fractions a common denominator of 54, you then add the negative 45/54 and the positive 48/ 54 and you get 3/54, then you divide the 3/54 by 9/54 and you get 9/3, which is the same thing as 3.
So the answer is 3
