Write out your expression. Distribute (multiply -3 by the numbers inside the parenthesis you should now have 12y + -9 + 7y. Add the like terms. You should get 19y + -9 or 19y - 9.

Answer 2

For this case we must simplify the following expression:

`-3 (-4y + 3) + 7y`

We apply distributive property to the terms within parentheses taking into account that:
`- * - = +\\- * + = -`

So:

`12y-9 + 7y =`

We add similar terms and finally we have:

`19y-9`

ANswer:

`19y-9`
