Question

The product of 2 integers is 72. One number is two less than five times the other. Which equation can be used?

Answer 1

should be (5y-2)y = 72

Explanation:

since the product of the two is 72, it's true that xy = 72. and it is also true that x is equal to five times y minus 2, so you can rewrite x as 5y-2. plug that in for x in the first equation, and you're set. hope this helps :)
