Question 350403
{{{33+13k=-1(5k+21)}}} Start with the given equation.



{{{33+13k=-5k-21}}} Distribute.



{{{13k=-5k-21-33}}} Subtract {{{33}}} from both sides.



{{{13k+5k=-21-33}}} Add {{{5k}}} to both sides.



{{{18k=-21-33}}} Combine like terms on the left side.



{{{18k=-54}}} Combine like terms on the right side.



{{{k=(-54)/(18)}}} Divide both sides by {{{18}}} to isolate {{{k}}}.



{{{k=-3}}} Reduce.

Answer:


So the solution is {{{k=-3}}}
