See a solution process below:

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 $color(red)(6)$ from each side of the equation to solve for $n$ while keeping the equation balanced:

$n + 6 - color(red)(6) = 20 - color(red)(6)$

$n + 0 = 14$

$n = 14$

$14$

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

$x+6=20$

$=>x+6-6=20-6$

$=>x=14$

Hope, it helps you!
