Question

What is 15(2x – 3y + 5x) = ?

Answer 1

Answer: 105x + -45y

Step-by-step explanation: Since there are three terms inside the parentheses in this problem, the 15 distributes through all three terms.

Before distributing however, change the -3y to plus a negative 3y.

So we have 15(2x) + 15(-3y) + 15(5x).

This simplifies to 30x + -45y + 75x.

Now combine like terms to get 105x + -45y.
