For this case we must combine similar terms to find an expression equivalent to a function of the form [tex]f (y) = 9y + y[/tex]
Adding (Equal signs are added and the same sign is placed):
[tex]f (y) = 10y[/tex]
Thus, an expression equivalent to [tex]9y + y[/tex] is [tex]10y[/tex]
Answer:
[tex]9y + y = 10y[/tex]
