The solution is the intersection point of the 2 lines.

The given two equations are:


\begin{gathered} y=-(2)/(3)x+3 \\ \text{and} \\ y=(3)/(2)x-2 \end{gathered}

Equating both equations, we can solve for x:


\begin{gathered} -(2)/(3)x+3=(3)/(2)x-2 \\ 3+2=(3)/(2)x+(2)/(3)x \\ 5=(13)/(6)x \\ x=(5)/((13)/(6)) \\ x=5*(6)/(13) \\ x=(30)/(13) \end{gathered}

Substituting this value into the second equation, we can find y:


\begin{gathered} y=(3)/(2)x-2 \\ y=(3)/(2)((30)/(13))-2 \\ y=(90)/(26)-2 \\ y=(45)/(13)-(26)/(13) \\ y=(19)/(13) \end{gathered}

The solution set or intersecting point is:


(x,y)=((30)/(13),(19)/(13))

Converting to decimal and rounding we can say:

(x, y) = (2.3, 1.5)
