Answer:

The answer is #11#.

Explanation:

First off, we're going to have to plot out the question -

#x - 30 = 14 - 3x#

First, what I want to do is to get all the numbers to one side, and all the unknown variables to the other, so what I'm going to do is add #30# to each side of the equal mark, I also want to add #3x# to both sides, now what I have is

#4x = 44#

After that, we divide #x# by #4# to get #1x#, and we do that to #44# too, so we get.

#x = 11#
