Answer:

I HOPE IT WILL HELP YOU.

Answer 2

Answer:

14

Step-by-step 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 6 from each side of the equation to solve for n while keeping the equation balanced:

n+6−6=20−6

n+0=14

n=14
