Hey there!
The simplified expression is 3x + 7y
To simplify this, we must add like terms. We can use the Commutative Property of addition to move the like terms together:
7x - x + 3x + 5y + 2y
Now, we can use the Associative Property to group the numbers:
(7x - x + 3x) + (5y +2y)
Now, we add the terms in the parentheses:
<u><em>3x + 7y</em></u>
<u><em></em></u>
Hope it helps and have a great day!!!
