Solution - Linear equations with one unknown

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     4^2*x-(12)=0 

Step by step solution :

Step  1  :

 1.1     4 = 22

(4)² = (2²)² = 2⁴

Equation at the end of step  1  :

  (24 • x) -  12  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   16x - 12  =   4 • (4x - 3) 

Equation at the end of step  3  :

  4 • (4x - 3)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    4   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 4.2      Solve  :    4x-3 = 0 

 Add  3  to both sides of the equation : 
                      4x = 3
Divide both sides of the equation by 4:
                     x = 3/4 = 0.750
