# A number increased by 6 equals 20?

Feb 20, 2018

See a solution process below:

#### Explanation:

Let's call "A number": $n$

"increased by" means to have it added to. So, we can write:

$n +$

It is increased by "6" so can continue to write:

$n + 6$

And, it "equals 20" so can complete this as:

$n + 6 = 20$

If we want to solve this we can subtract $\textcolor{red}{6}$ from each side of the equation to solve for $n$ while keeping the equation balanced:

$n + 6 - \textcolor{red}{6} = 20 - \textcolor{red}{6}$

$n + 0 = 14$

$n = 14$

$14$

#### Explanation:

Let the number be $x$. Then, $x$ is increased by $6$. So

$x + 6 = 20$

$\implies x + 6 - 6 = 20 - 6$

$\implies x = 14$
