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 :

                     7^2*x-(20)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (72 • x) -  20  = 0 

Step  2  :

Equation at the end of step  2  :

  49x - 20  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    49x-20 = 0 

 Add  20  to both sides of the equation : 
                      49x = 20
Divide both sides of the equation by 49:
                     x = 20/49 = 0.408
