Question

Combine like terms. What is a simpler form of the expression?

−3(−4y+3)+7y

Answer 1

To simplify the expression -3(-4y+3)+7y, we first distribute -3 to both terms inside the parentheses:

-3 * -4y = 12y
-3 * 3 = -9

So the expression becomes:

12y - 9 + 7y

Next, we can combine like terms by adding the coefficients of the y terms:

12y + 7y = 19y

So the expression simplifies to:

19y - 9
