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 :

                     15^2*x-(36)=0 

Step by step solution :

Step  1  :

 1.1     15 = 3•5

(15)² = (3•5)² = 3² • 5²

Equation at the end of step  1  :

  ((32•52) • x) -  36  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   225x - 36  =   9 • (25x - 4) 

Equation at the end of step  3  :

  9 • (25x - 4)  = 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  :    25x-4 = 0 

 Add  4  to both sides of the equation : 
                      25x = 4
Divide both sides of the equation by 25:
                     x = 4/25 = 0.160
