Question

Twelve (12) more than a number is five (5). What is the number?

Answer 1

ANSWER

$-7$

EXPLANATION

Let the number be x.

Twelve more than the number is:

$12+x$

That value is equal to five. This implies that:

$12+x=5$

To find the number (x), subtract 12 from both sides of the equation:

$\begin{gathered} 12+x-12=5-12 \\ x=-7 \end{gathered}$

That is the number.
