3O+5P=7.6 MULTIPLY THIS EQUATION BY 5
5O+4P=7.9 MULTIPLY THIS EQUATION BY -3 & ADD THEM
15O+25P=38
-15O-12P=-23.7
--------------------------
13P=14.3
P=14.3/13
P=1.10 PRICE OF ONE PANCAKE.
3O+5*1.1=7.6
3O+5.5=7.6
3O=7.6-5.5
3O=2.1
O=2.1/7
O=.30 COST OF ONE ORANGE.
1.10+.30=$1.40 COST OF 1 ORANGE & 1 PANCAKE.
