You are told that there are three convenient units for some
calculations you must perform: baks, beks, and buks. Each unit is
represented symbolically by its vowel: baks by A, beks by E, and
buks by U. Match the English statement of the relationship between
the three units on the left with the symbolic formula on the right. --
CORRECT ANSWER--Baks are equal to two baks plus three beks:
A=2U + 3E.

, Baks are equal to two buks divided by three beks: A=2U/3E.
Baks are equal to three beks divided by two buks: A= 3E/2U
Baks are equal to two buks times three beks: A= 6UE.
