Answer:
-y + 63
Step-by-step explanation:
Let's start like by solving the order of operations, and then add our Y's:
7y + 7 + −8y + 56
Adding:
+63 - y
Simplifying:
Thus, our answer is -y + 63
-y+63
You need to distribute the -8 by multiplying it to y and -7 therefore making 7y+7-y+56. Then you subtract 7y by 8y and then add 7 with 56
As a result, you then get -y + 63
