3x + 5=3x - 5
use the distributive property
combine alike terms
add the negative number to the other side
combine alike terms
then divide on both sides to get the variable by itself
9 .... juhh add the long sides all together !!
Let's take the non-linear equation:

First Make The Equation To Be In Terms of Y
*Divide Both sides by


*Simplify

You shouldn't keep a radical in the denominator, however we leave it for the purpose of the reciprocal.
*Take The Reciprocal Of Both Sides

A Linear Equation Takes The Format:

So,




Resulting in :
