Simplify 7y+7-8 (y-7)

-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:

-y + 63

Thus, our answer is - y + 63

-y+63

Step-by-step explanation:

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
