Answer
$(-4,-12)$ is a solution,
$(2,3)$ and $(3,2)$ are not
Work Step by Step
An ordered pair (a,b) is a solution of an equation in x and y if,
substituting a for x and b for y,
we obtain an equation that holds true.
Another way of stating this is that (a,b) satisfies the equation.
---
$(x,y)=(2,3)$
$3=3(2) \qquad $.... false, not a solution
$(x,y)=(3,2)$
$2=3(3) \qquad $.... false, not a solution
$(x,y)=(-4,-12)$
$-12=3(-4) \qquad $.... true, a solution
