Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  9 • (2j + 1) -  7j  = 0 

Step  2  :

Equation at the end of step  2  :

  11j + 9  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    11j+9 = 0 

 Subtract  9  from both sides of the equation : 
                      11j = -9
Divide both sides of the equation by 11:
                     j = -9/11 = -0.818
