*Five times a number is divided by 7 more than the original number. If the result is 12, then what was the original number?*

Let X stand for the original number.

The terms of the problem (5 • X) / (X + 7) = 12

Multiply both sides by (X + 7) 5X = 12X + 84

Subtract 12X from both sides –7X = 84

Divide both sides by –7 **X = –12**

Check answer as follows:

Plug –12 into original equation (5 • –12) / (–12 + 7) = 12

(–60) / (–5) = 12 answer is confirmed
