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 :

                     9^2*x-(45)=0 

Step by step solution :

Step  1  :

 1.1     9 = 32

(9)² = (3²)² = 3⁴

Equation at the end of step  1  :

  (34 • x) -  45  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   81x - 45  =   9 • (9x - 5) 

Equation at the end of step  3  :

  9 • (9x - 5)  = 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  :    9x-5 = 0 

 Add  5  to both sides of the equation : 
                      9x = 5
Divide both sides of the equation by 9:
                     x = 5/9 = 0.556
