6x + 5y= 15

step one: multiply the first equation by (-2)
so u get -2*(3x+2y=9)  ------> -6x-4y=-18
                  6x+5y=15                 6x+5y=15
step two: add both equations        ----------
                                                    0+y=-3
                                                        y=-3
now that u have the value of y u can substitute that into one of the equations and find the value of x
