2%284-2r%29=-2%28r%2B5%29 Start with the given equation.


8-4r=-2r-10 Distribute.


-4r=-2r-10-8 Subtract 8 from both sides.


-4r%2B2r=-10-8 Add 2r to both sides.


-2r=-10-8 Combine like terms on the left side.


-2r=-18 Combine like terms on the right side.


r=%28-18%29%2F%28-2%29 Divide both sides by -2 to isolate r.


r=9 Reduce.
