Final answer:
The answer to the expression 3x + 4y + 2x + 5y is obtained by combining like terms, resulting in the simplified form 5x + 9y.
Step-by-step explanation:
The solution to the mathematical expression 3x + 4y + 2x + 5y involves combining like terms. In mathematics, like terms have the same variables raised to the same powers, which means you can add or subtract them from each other. Here, we can combine the terms with x and the terms with y.
First, combine the x terms:
3x + 2x = 5x
Next, combine the y terms:
4y + 5y = 9y
Now that we have combined the like terms, we simply put them together to get the final simplified expression:
5x + 9y
