Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

            1
 Simplify   —
            5

Equation at the end of step  1  :

  1
  — • (10k + 15)  = 0 
  5

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   10k + 15  =   5 • (2k + 3) 

Equation at the end of step  3  :

  2k + 3  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    2k+3 = 0 

 Subtract  3  from both sides of the equation : 
                      2k = -3
Divide both sides of the equation by 2:
                     k = -3/2 = -1.500
