Lee is thinking of two numbers. The product is 18;
the quotient is 2. What are the two numbers?
------
Equations:
xy = 18
x/y = 2
----
Solve for "x" and substitute to solve for "y":
----
x = 18/y
---
(18/y)/y = 2
---
18/y = 2y
---
18 = 2y^2
y^2 = 9
y = 3 or -3.
------
Solve for "x"
xy = 18
If y = 3, x = 6
If y = -3, x = -6
