Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

            15a
 Simplify   ———
             3 

Equation at the end of step  1  :

  ((8a + 9) +  5a) -  7  = 0 

Step  2  :

Equation at the end of step  2  :

  13a + 2  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    13a+2 = 0 

 Subtract  2  from both sides of the equation : 
                      13a = -2
Divide both sides of the equation by 13:
                     a = -2/13 = -0.154
