7(5x+3y=27)
-5(7x+9y=51)
———————
35x+21y=189
-35x-45y=-255
————————
-24y=-66
Y=-66/-24
Y=2.75
——————-
Now replace Y with one of the equations to find x
—————
5x+3(2.75)=27
5x+8.25=27
5x=27-8.25
X=18.75/5
X=3.75
——————
Final answer =
X=3.75
Y=2.75
5 pounds= 80 ounces
Since each piece weighs 2 ounces you divide 80 by 2 and get 40.
So, there are 40 slices of cheese
