A person drives 300 miles at a constant speed of 55 mph. The equation R = 300 - 55h represents the number of miles remaining after h hours. Which represents the equation when solved for h?

h  = -     +

Step-by-step explanation:

The expression is given as:

       R  = 300  - 55h

Solving for h implies making h the subject of the expression:

    R = 300 - 55h

 First add -300 to both sides of the expression;

   R + (-300)  = 300   - 55h  + (-300)

     R - 300  = -55h

Now divide through by (-55)

           -        =    

          h  = -     +
