0.25r- 0.125 + 0.5r= 0.5 +r
0.75r- 0.125= 0.5 +r       ------ combine like terms
        + 0.125 + 0.125      ------- isolate the variable
0.75r = 0.625 + r
- r                     - r          ------- combine like terms
-0.25r= 0.625
/-0.25   /-0.25               -------divide both sides by -0.25
         r= -2.5
