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 :

                     42-(42+9*b)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    -9b = 0 

 Multiply both sides of the equation by (-1) :  9b = 0


Divide both sides of the equation by 9:
                     b = 0
