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 :

                     20+7*k-(8*(k+2))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (7k + 20) -  8 • (k + 2)  = 0 

Step  2  :

Equation at the end of step  2  :

  4 - k  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    -k+4 = 0 

 Subtract  4  from both sides of the equation : 
                      -k = -4
Multiply both sides of the equation by (-1) :  k = 4
