we have many ways to start this problem ,the easiest one is adding 
Let  x + 3y = 9 be equation 1
and let 3x – 3y = –13 be equation 2
By adding 1+2 u get :    x+3y+3x-3y=9+-13
                                     4x=-4
                                       x=-1 
now after u got the x value go and substitute in any equation and let it be equation 1 (x+3y=9) put x=-1 , -1+3y=9 , 3y=9+1 ,3y=10 ,y=10/3
