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*r-7-(2*r-18)=0 

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

 1.1      Solve  :    5r+11 = 0 

 Subtract  11  from both sides of the equation : 
                      5r = -11
Divide both sides of the equation by 5:
                     r = -11/5 = -2.200
