Question

What is the simplified result of following the steps below in order?

(1)	add 5y to 2x
(2)	multiply the sum by 3
(3)	subtract x + y from the product
A. 5x + 14y 
B. 5x + 16y 
C. 5x + 5y

Just do it one step at a time.

(1) add 5y to 2x $\rightarrow $ 2x + 5y

(2) multiply the sum by 3 $ \rightarrow$ 3(2x + 5y)
Now use the distributive property to simplify this.
