If the ratio of 7 less than a number and 7 more than the number 2, what is the number?

Step-by-step explanation:

I assume you mean "if the ratio of 7 less than a number and 7 more than the number is 2".

Let x be the number.

Ratio is division.

(x-7) / (x+7) = 2

Multiply by (x+7) on each side:

x-7=2 (x+7) = 2x+14

Add 7 on each side

x=2x+21

Subtract 2

-x=21

x=-21
