Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -2s - 5  =   -1 • (2s + 5) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -2s-5 = 0 

 Add  5  to both sides of the equation : 
                      -2s = 5
Multiply both sides of the equation by (-1) :  2s = -5


Divide both sides of the equation by 2:
                     s = -5/2 = -2.500
