Answer:(4,1)
Step-by-step explanation:
-x+3y=-1
X-2y= 2
______
Change second equation move all to right side to leave x on left side .
-x+3y= -1
X= 2y+2
Now substitute second equation that you made into first equation to find y.
-(2y+2)+3y= -1
-2y-2+3y=-1
Y-2=-1
Y= -1+2
Y= 1
Now substitute your answer of y into second equation you created to find x .
X= 2y+2
X= 2(1)+2
X=2+2
X=4
