Two step equation - 10 = 10 (k - 9)

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
