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 :

                     -7+4*c-(7*c+6)=0 

Step by step solution :

Step  1  :

Pulling out like terms :

 1.1     Pull out like factors :

   -13 - 3c  =   -1 • (3c + 13) 

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

 2.1      Solve  :    -3c-13 = 0 

 Add  13  to both sides of the equation : 
                      -3c = 13
Multiply both sides of the equation by (-1) :  3c = -13


Divide both sides of the equation by 3:
                     c = -13/3 = -4.333
