You can put this solution on YOUR website! Solve each system by the substitution method.
x+3y=2
and
-x+y=1
----------------
Solve the 2nd equation for "y":
y = x+1
---------------
Substitute into the 1st equation:
x + 3(x+1) = 2
x + 3x + 3 = 2
4x = -1
x = -1/4
-----------------------------
Since y = x+1, y = -1/4 +1
y = 3/4
