#x = 34#

Explanation:

You want #x# to be alone on one side, so you add #14#:
(If you can't do it in your head, you write #+ 14# on both sides)

#x - 14 = 20#

#x - 14 + 14 = 20 + 14#

#x = 34#

Solve for #x#.

Explanation:

add 14 to both sides to get X by its self

#x-14 +14 = 20 +14#

#x + 0 = 34 #

#x=34#

#x=34#

Explanation:

As with any given letter in algebra, we are trying to solve to find the value of the letter.

Given:

#x-14=20#

We want to find #x# on its own, and we do the opposite to the operation given.

The opposite to #-14# is to #+14#, remember that these cancel out, and what you do to one side you MUST do to the other.

#x-14=20 -> x=20+14 -> x=34#

We can always check this.

Given:

#x-14=20#

Plugging in the value of #x#

#34-14=20# which is true, therefore we are correct.

#x=34#

Explanation:

We want to solve for #x#, and at the moment, #14# is being subtracted from it. To isolate it, we must do the inverse operation.

This would be adding #14# to both sides. We get:

#xcancel(-14+14)=20+14#

#=>x=34#

To check our answer, we can plug in #34# for #x#. We get:

#34-14#, which is indeed equal to #20#.
