-%289%2B10k%29%2B6%28-9k%2B12%29=-4k%2B10-7 Start with the given equation.


-9-10k-54k%2B72=-4k%2B10-7 Distribute.


-64k%2B63=-4k%2B10-7 Combine like terms on the left side.


-64k%2B63=-4k%2B3 Combine like terms on the right side.


-64k=-4k%2B3-63 Subtract 63 from both sides.


-64k%2B4k=3-63 Add 4k to both sides.


-60k=3-63 Combine like terms on the left side.


-60k=-60 Combine like terms on the right side.


k=%28-60%29%2F%28-60%29 Divide both sides by -60 to isolate k.


k=1 Reduce.
