#### Answer

$-6y+3$

#### Work Step by Step

The commutative property holds that $a+b=b+a$ (for real numbers $a$ and $b$).
Therefore, we know that $-12y+4y+3+2y=-12y+4y+2y+3$.
The distributive property holds that $a(b+c)=ab+ac$ (for real numbers $a$, $b$, and $c$).
Therefore, $-12y+4y+2y+3=(-12+4+2)y+3=(-6)y+3=-6y+3$.
