Solution - Linear equations with one unknown

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x0"   was replaced by   "x^0". 

Rearrange:

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

                     4*x^0*y-(12)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   4y - 12  =   4 • (y - 3) 

Equation at the end of step  2  :

  4 • (y - 3)  = 0 

Step  3  :

Equations which are never true :

 3.1      Solve :    4   =  0

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

Solving a Single Variable Equation :

 3.2      Solve  :    y-3 = 0 

 Add  3  to both sides of the equation : 
                      y = 3
