Explanation:
First off, we're going to have to plot out the question -
x
−
30
=
14
−
3
x
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
3
x
to both sides, now what I have is
4
x
=
44
After that, we divide
x
by
4
to get
1
x
, and we do that to
44
too, so we get.
x
=
11
