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 :

                     7^3*x-(400)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (73 • x) -  400  = 0 

Step  2  :

Equation at the end of step  2  :

  343x - 400  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    343x-400 = 0 

 Add  400  to both sides of the equation : 
                      343x = 400
Divide both sides of the equation by 343:
                     x = 400/343 = 1.166
