I really need help due today will fan!! Solve, showing all steps. Hint - Your first step should be to combine like terms. 7y – 11 – 10y + 3 = 7

OpenStudy (anonymous):

OpenStudy (anonymous):

First, which ones look similar?

OpenStudy (spicytaco1):

7y and 10y

OpenStudy (anonymous):

ok so therefore you have 7y and -10y, add it. 7y+-10y

OpenStudy (spicytaco1):

17y?

OpenStudy (anonymous):

no, whats 7-10

OpenStudy (spicytaco1):

OpenStudy (anonymous):

-3y

OpenStudy (anonymous):
