X = 3
y = -1 

get the x or y by itself first (second eq. is easier)
So, x + 2y = 1
          -2y     -2y
Now we get: 
x = -2y +1 Plug it into the other equation.

2x + 3y = 3
2(-2y +1) + 3y = 3
-4y + 2 + 3y = 3
-1y +2 = 3
+1y -3    -3  +1 y

y = -1 (plug into either eq to get x)

<span>x + 2y = 1
</span>x+2(-1) = 1
x-2=1
 +2  +2

x = 3
