Answer

$2b+3a$

Work Step by Step

The commutative property of addition holds that $a+b=b+a$, for real numbers a and b. However, since the terms used in this example are a and b, we will say that $x+y=y+a$ to avoid confusion. In this example, we can set $3a+2b=x+y$. So, $x=3a$ and $y=2b$. Therefore, $y+x=2b+3a$.
