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 :

                     2*a+42+47-(5*a)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    -3a+89 = 0 

 Subtract  89  from both sides of the equation : 
                      -3a = -89
Multiply both sides of the equation by (-1) :  3a = 89


Divide both sides of the equation by 3:
                     a = 89/3 = 29.667
