$(-3,-2)$
Graphing $x=y-1$ Set $y=4 \Rightarrow x=3 \qquad$... $(3,4)$ Set $y=0 \Rightarrow x=-1 \qquad$... $(-1,0)$ Graphing $2x=3y$ Set y=$0 \Rightarrow x=0 \qquad$... $(0,0)$ Set y=$2 \Rightarrow x=3 \qquad$... $(3,2)$ Graphically solving: $x=-3,\ y=-2$. Checking:$\qquad \left\{\begin{array}{lll} -3 =-2-1 & & \\ & & \\ 2(-3)=3(-2) & & \end{array}\right.$ both equations are satisfied, $(-3,-2)$ is the solution.
