4 x-2 z = b-2 solve for x

Question

4 x-2 z = b-2

Answer 1

4x - 2z = b-2. 

In order to solve for x, shift all the other terms to the R.H.S (Right Hand Side of the equation).

4x = b-2 +2z

Now divide both sides by 4. 

x = b/4  -2/4 + 2z/4  (Now we have to simplify or reduce the fractions)

   =  b/4 -1/2 + z/2    which could be rewritten as 

   =  b/4 + z/2 - 1/2.
