Answer 1

Ah, for this question, you will have to combine like terms and use the addition property of equality in order to find your answer:

First, combine all like terms. In this case, like terms only have to be combined on the right side of the equation.

`6+(-12)`

Remember: a negative times a positive equals a negative!

`6-12=-6`

`k-12=-6`

Now, use the addition property of equality to add 12 on both sides in order to cancel out the -12.

`k=6`

C would be your final answer.

Answer 2

k-12 = 6+ (-12)

k-12=-6

add 12 to both sides

k =6

C
