Question 148180
The sum of two numbers is 73. The second is 7 more than 5 times the first. What are the two numbers? 
----------------------
Using two variables:
EQUATIONS:
x + y = 73
y = 5x + 7 
-------------
Substitute the 2nd into the 1st to get:
x + (5x+7) = 73
6x = 66
x = 11
-------
Substitute into y = 5x+7 to solve for "y":
y = 5*11+7
y = 62
===================
Using one variable:
Let 1st be "x"; 
then 2nd = 5x+7
EQUATION:
x + 5x+7 = 73
6x + 7 = 73
6x = 66
x = 11
then y = 62
