Answer:
k=8
Step-by-step explanation:
-10=10(k-9)
Firstly to solve this question, we will have to deal with the bracket
After opening the bracket ,we can then go ahead to solve the problem
Here it's goes
-10=10k-90
To solve further,add 90 to both sides
-10+90=10k-90+90
It will be observed that 90 on the right side be eliminated
80=10k
To continue with the solution we will have to divide both sides by 10
k=8
Therefore the solution to the given question is 8
