20=
20=
\,\,-10r
−10r

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -10*r-20-(-20)=0

Step by step solution :

Solving a Single Variable Equation:

1.1      Solve  :    -10r = 0

Multiply both sides of the equation by (-1) :  10r = 0

Divide both sides of the equation by 10:

                    r = 0

One solution was found :

r = 0
