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 :

                     3^8*y-(72)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (38 • y) -  72  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   6561y - 72  =   9 • (729y - 8) 

Equation at the end of step  3  :

  9 • (729y - 8)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    9   =  0

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

Solving a Single Variable Equation :

 4.2      Solve  :    729y-8 = 0 

 Add  8  to both sides of the equation : 
                      729y = 8
Divide both sides of the equation by 729:
                     y = 8/729 = 0.011
