Substitute first equation in second equation and solve for x..
Given equations are x+y=5. Then y=5-x
And 2x-y=-2
Sp 2x-(5-x)=-2 expand the equation
2x-5+x=-2
3x-5=-2
Add 5 on both sides
3x-5+5=-2+5
3x=3
So x = 3 3 = 1
Substitute x=7/4 in the second equation and solve for y
So 2(1)-y=-2
2-y=-2. subract 2 on both sides
2-y-2=-2-2
-y=-4
So y=4
Result:
(x,y)=(1,4)
