You can put this solution on YOUR website!
equation 1x=y-8+
equation 2-x-y=0
Substitute eq 1 to eq 2
+-x-y=0 x=y-8
+-%28y-8%29-y=0+
+-y%2B8-y=0
+-2y=-8
+-2y%2F-2=-8%2F-2
+highlight+%28y=4%29+
+x=y-8 y=4
+x=4-8
+highlight+%28x=-4%29

x = y - 8
-x - y = 0
---
put the system of linear equations into standard form
---
x - y = -8
-x - y = 0
---
