Question 226452


{{{-10(r-6)=90}}} Start with the given equation.



{{{-10r+60=90}}} Distribute.



{{{-10r=90-60}}} Subtract {{{60}}} from both sides.



{{{-10r=30}}} Combine like terms on the right side.



{{{r=(30)/(-10)}}} Divide both sides by {{{-10}}} to isolate {{{r}}}.



{{{r=-3}}} Reduce.

Answer:


So the answer is {{{r=-3}}}
