Question 641959
{{{2(4-2r)=-2(r+5)}}} Start with the given equation.



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



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



{{{-4r+2r=-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=(-18)/(-2)}}} Divide both sides by {{{-2}}} to isolate {{{r}}}.



{{{r=9}}} Reduce.

Answer:


So the solution is {{{r=9}}}
