{{{16+8r-4r+4=24}}} Start with the given equation.



{{{4r+20=24}}} Combine like terms on the left side.



{{{4r=24-20}}} Subtract {{{20}}} from both sides.



{{{4r=4}}} Combine like terms on the right side.



{{{r=(4)/(4)}}} Divide both sides by {{{4}}} to isolate {{{r}}}.



{{{r=1}}} Reduce.
