Question 148323
The quotient of 2 numbers is 5, their difference is 10, what are these numbers?
-----------------
x/y = 5
x-y = 10
------------
Change form:
x = 5y
Substitute:
5y-y=10
4y=10
y = 5/2
---------
Substitute 
x = 5(5/2)
x = 25/2
--------------
Checking: 
x/y = (25/2)/(5/2) = 5; true

x-y = (25/2)-(5/2) = 20/2 = 10; true
