+4x%2B6y=62
-6x%2B6y=-18+
____________________subtract
+4x%2B6y-%28-6x%2B6y%29=62-%28-18%29
+4x%2B6y%2B6x-6y=62%2B18
+4x%2Bcross%286y%29%2B6x-cross%286y%29=80
+10x=80
+x=80%2F10
+highlight%28x=8%29
now find y

+4x%2B6y=62 ...plug in x=8
+4%2A8%2B6y=62
+32%2B6y=62
+6y=62-32
+6y=30
+y=30%2F6
+highlight%28y=5%29
