Question 196978
The average of two numbers is 7. Find the numbers if three times one of the numbers is one half the other number.
I tried using substitution from the two equations given, which I think are :
(x + y) / 2 = 7 and
3x = 1/2y
-----------------------
Those are good equations.

Rearrange to get:
x + y = 14
y = 6x
-------------
Substitute to solve for "x":
x + 6x = 14
x = 2 (one of the numbers)
y = 12 (the other number)
