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*(p-5)-(2*(10+2*p))=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   10 + 2p  =   2 • (p + 5) 

Equation at the end of step  2  :

  (2 • (p - 5)) -  4 • (p + 5)  = 0 

Step  3  :

Equation at the end of step  3  :

  2 • (p - 5) -  4 • (p + 5)  = 0 

Step  4  :

Step  5  :

Pulling out like terms :

 5.1     Pull out like factors :

   -2p - 30  =   -2 • (p + 15) 

Equation at the end of step  5  :

  -2 • (p + 15)  = 0 

Step  6  :

Equations which are never true :

 6.1      Solve :    -2   =  0

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

Solving a Single Variable Equation :

 6.2      Solve  :    p+15 = 0 

 Subtract  15  from both sides of the equation : 
                      p = -15
