Let's solve your equation step-by-step.
Step 1: Step 1: Simplify both sides of the equation.9(k−5)−12=7k−(−6−2k)9(k−5)−12=7k+−1(−6−2k)(Distribute the Negative Sign)
9(k−5)−12=7k+(−1)(−6)+−1(−2k)
9(k−5)−12=7k+6+2k
(9)(k)+(9)(−5)+−12=7k+6+2k(Distribute)
9k+−45+−12=7k+6+2k(9k)+(−45+−12)=(7k+2k)+(6)(Combine Like Terms)
9k+−57=9k+69k−57=9k+6
Step 2: Subtract 9k from both sides.
9k−57−9k=9k+6−9k−57=6Step 3: Add 57 to both sides.−57+57=6+57=63

9(k - 5) - 12= 7k -(-6 - 2k)
Steps
First, expand 9(k - 5) - 12: 9k - 57
and expand 7k - (-6 - 2k): 9k + 6
which is...
9k - 57 = 9k + 6
Next, add 57 to both sides
9k - 57 + 57 = 9k + 6 + 57
Then simplify,
9k = 9k + 63
Next, subtract 9k from both sides
9k - 9k = 9k + 63 - 9k
Simplify,
0 = 63
The final answer is that the sides aren't equal... which is no solution.
