You said            -14 + 6x + 7 - 2x  =  1 + 5x

The first thing we absolutely must do is clean up
that ugly mess on the left side.

Add up all the Xs:   6x - 2x =  4x
Add up the just-plain-numbers:      -14 + 7  =  7
The left side is actually      4x +  7

NOW the equation is much prettier:

                                             4x + 7  =  1 + 5x
Subtract  4x
from each side:                           7  =  1 +  x

Subtract  1  from each side:       6  =        x


I bet that wasn't as scary as you expected.
