Question 249094
One number is 5 more than another. 5 times the smaller equals 4 times the larger. Find the numbers. 
----------------------
Equation:
x = y+5
Note: y is the smaller number.
------------
5y = 4x
-----------------
Substitute for "x" and solve for "y":
5y = 4*(y+5)
5y = 4y+20
y = 20 (smaller number)
-----
x = y+5 = 25 (larger number)
