Answer:

19y+ -9

Step-by-step explanation:

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.

For this case we must simplify the following expression:

[tex]-3 (-4y + 3) + 7y[/tex]

We apply distributive property to the terms within parentheses taking into account that:[tex]- * - = +\\- * + = -[/tex]

So:

[tex]12y-9 + 7y =[/tex]

We add similar terms and finally we have:

[tex]19y-9[/tex]

ANswer:

[tex]19y-9[/tex]
