Answer:
It is a linear equation in k. It might be referred to as a "3-step" or maybe even a "4-step" linear equation.
The solution is ... k = -17/11
Explanation:
Start by eliminating parentheses. Since the numbers on the right are both even, you can do this by dividing by -2.
9k +8 = -9 -2k
Add 2k-8:
11k = -17
Divide by the coefficient of k.
k = -17/11
