You can put this solution on YOUR website! When a student added 14 to a number, the result is 1/3 of the number. What is the number?
----
Let the number be "x"::
Equation:
x + 14 = (1/3)x
------
Subtract (1/3)x from both sides of the equation::
Subtract 14 from both sides of the equation::
-------------
(2/3)x = -14
----
Divide both sides of the equation by (2/3) to get:
x = (-14)/(2/3) = -7*3 = -21
