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 :

                     -2*(n+3)-(13)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (0 -  2 • (n + 3)) -  13  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   -2n - 19  =   -1 • (2n + 19) 

Equation at the end of step  3  :

  -2n - 19  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    -2n-19 = 0 

 Add  19  to both sides of the equation : 
                      -2n = 19
Multiply both sides of the equation by (-1) :  2n = -19


Divide both sides of the equation by 2:
                     n = -19/2 = -9.500
