Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   4 + 2k  =   2 • (k + 2) 

Equation at the end of step  2  :

  12 • (k + 2) +  3k  = 0 

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   15k + 24  =   3 • (5k + 8) 

Equation at the end of step  4  :

  3 • (5k + 8)  = 0 

Step  5  :

Equations which are never true :

 5.1      Solve :    3   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 5.2      Solve  :    5k+8 = 0 

 Subtract  8  from both sides of the equation : 
                      5k = -8
Divide both sides of the equation by 5:
                     k = -8/5 = -1.600
