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!
