Divide both sides by 5: |−9k − 1| = 2.
So −9k − 1 = 2 or −9k − 1 = −2.
If −9k − 1 = 2 → −9k = 3 → k = −1/3.
If −9k − 1 = −2 → −9k = −1 → k = 1/9.
Thus there are 2 solutions: k = −1/3 and k = 1/9.
So −9k − 1 = 2 or −9k − 1 = −2.
If −9k − 1 = 2 → −9k = 3 → k = −1/3.
If −9k − 1 = −2 → −9k = −1 → k = 1/9.
Thus there are 2 solutions: k = −1/3 and k = 1/9.
