Answer:
There is no "=" sign, so this is just an expression. To solve means to simplify by combining like terms, where possible.
5y+6-(5y+y) = -y + 6
Explanation:
5y+6-(5y+y)
5y+6-(6y) [Simplify by combining like terms]
5y+6-6y [Remove the parentheses, remembering to multiply 6y by -1]
-y + 6 [Combine like terms]
