Solution - Linear equations with one unknown

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -5x - 12  =   -1 • (5x + 12) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -5x-12 = 0 

 Add  12  to both sides of the equation : 
                      -5x = 12
Multiply both sides of the equation by (-1) :  5x = -12


Divide both sides of the equation by 5:
                     x = -12/5 = -2.400
