If 5 is added to a number and the sum is tripled, the result is 27 more than than number? Find the number

Apr 19, 2018

The answer is $6$

Explanation:

Let that number be $x$.

You add $5$;

$x + 5$

The sum of $x$ and $5$ is tripled, so;

$3 \left(x + 5\right)$

The result of the above equation is $27$ more than $x$, therefore;

$3 \left(x + 5\right) = x + 27$

$\implies 3 x + 15 = x + 27$

$\implies 2 x = 12$

Therefore

$x = 6$
