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 :

                     5*(y-3)-(2*(y+12))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (5 • (y - 3)) -  2 • (y + 12)  = 0 

Step  2  :

Equation at the end of step  2  :

  5 • (y - 3) -  2 • (y + 12)  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   3y - 39  =   3 • (y - 13) 

Equation at the end of step  4  :

  3 • (y - 13)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    3   =  0

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

Solving a Single Variable Equation :

 5.2      Solve  :    y-13 = 0 

 Add  13  to both sides of the equation : 
                      y = 13
