Answer
(3,1)
Work Step by Step
Add the 2 equations.
$\ \ x+3y=6$ multiply both sides by -1
$\underline{\ \ x-\ \ y=2}$
$-x-3y=-6$
$\underline{\ \ x-\ \ y\ \ =\ \ 2}$
$\ \ \ \ -4y\ \ \ =-4$ divide both sides by -4
$\ \ \ \ \ \ \ \ \ \ y\ \ \ \ \ \ \ =1$
Substitute and solve for x.
$x-y=2$
$x-1=2$
$x-1+1=2+1$
$x=3$
