What is 15 (2x - 3y + 5x) = ?

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.
