Question

— 3y +3y + у — 7y = identity and combine liked terms

Answer 1

To comibine liked terms we find the ones that have the same literal part and add the coefficients together

`\begin{gathered} -3y+3y+y-7y \\ (-3+3+1-7)y \\ -6y \end{gathered}`

this can also be seen as taking a common factor y and adding all the other terms together
