If the (-6 x 2 + 4x) means "multiply -6 by 2 and add 4x", you can solve this by simplifying the equations inside of the parentheses and on the right side of the equation. See below if you really meant (-6x2 + 4x). Be careful in either case with order of operations. Basic order of operations:
(1) Negation, e.g. -6.
(2) Parentheses.
(3) Multiplication & division, from left to right.
(4) Addition & subtraction, from left to right..
First, simplify (-6 x 2 + 4x) in both sets of parentheses. Do the multiplication by -6 first.
Second, simplify -3x + 2 - 3x + 2. This is easier if you group the x's and the constants, e.g. -3x - 3x + 2 + 2.
Once you've simplified the left-hand and right-hand sides of the equation, solve for ?. This might look more familiar if you use a different variable name instead of ?, i.e. nx instead of ?x.
If the original equation was in terms of x2, the process is similar.
Then the equation will be:
(-6x2 + 4x)/?x (-6x2 + 4x)/?x = -3x + 2 -3x + 2, or
(-6x2 + 4x)/?x (-6x2 + 4x)/?x = -3x -3x + 2 + 2.
First, recognize that you can divide (-6x2 + 4x) by ?x. Simplified, this is (-6x + 4) / ?. Do this for both quotients on the left-hand side.
If you divide both sides of the resulting equation by (-6x + 4), you will have an equation that you can convert to the form ? = ...
Note that there will be an x in the final answer.
