Ответ:
2x=y
z = 5/x
where y is the total amount he paid for the two packs of batteries, and z is the number of packs of batteries he bought out of $5. Technically, this problem is unsolvable. But, for educational purposes, let's just assume one of those variables that is likely to be given. Suppose two packs of batteries costs $2.4. Then,
2x = 2.4
x = 1.2
Each pack of battery costs $1.2. The number of batteries he could buy with $5 is
z = 5/1.2 = 4.167
At most, he could only buy 4 packs of batteries.
