Solving a Math Problem with Equations Containing 2 Variables III

Posted on January 21, 2010 by Fany Savina

Olly Ogre had thrice as many pickled human fingers as pickled human toes in his fridge. When his best friend, Izzy Imp, came over, Olly gave him 664 pickled human fingers. Now Olly has thrice as many pickled human toes as pickled human fingers. (i)How many toes and fingers did Olly have in his fridge before Izzy came over?

x=fingers

y=toes

x=3y

x-664=\frac{y}{3}

x-664=\frac{y}{3}

3(3y-664)=y

9y-1992=y

9y-y-1992=0

9y-y=1992

8y=1992

y=\frac{1992}{8}

y=249

x=3y

x=3(249)

x=747

(i)How many toes and fingers did Olly have in his fridge before Izzy came over?
= x+y=?

747+249=996
