Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.

We can find the solutions by simultaneously solving the two equations.

From first equation, the value of y comes out to be:

2x+3y=-3 \\  \\ 
3y=-3-2x \\  \\ 
y= \frac{-3-2x}{3}

Using this value of y in second equation, we get:

3x+5( \frac{-3-2x}{3} )=-9 \\  \\ 
9x-15-10x=-27 \\  \\ 
-x=-27+15 \\  \\ 
-x=-12 \\  \\ 
x=12

Using this value of x, we can find y:

y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9

Therefore, there is only one solution to the given equations is which is (12, -9)
