-3%28-7k-8%29=-28%2B8k Start with the given equation.


21k%2B24=-28%2B8k Distribute.


21k=-28%2B8k-24 Subtract 24 from both sides.


21k-8k=-28-24 Subtract 8k from both sides.


13k=-28-24 Combine like terms on the left side.


13k=-52 Combine like terms on the right side.


k=%28-52%29%2F%2813%29 Divide both sides by 13 to isolate k.


k=-4 Reduce.
