5 - 6 =  - 3k \\  - 1 =  - 3k \\  \frac{1}{3}  = k
First, we combine the terms on the left side of the equation to simplify the equation. Then we divide both sides by -3. k then equals 1/3.
To check, we plug in our value for k into the original equation:
5 - 6 =  - 3k \\ 5 - 6 =  - 3( \frac{1}{3} ) \\  - 1 =  - 1
We found k to be 1/3, so for every instance of k, we plug in 1/3. To simplify, we combine the left side to get -1, and we combine the right side to get -1.
Since -1 = -1, our solution is correct.

Joey has a pool in his backyard and he wants to build a fence around the entire area joeys backyard is 12 meters wide and 14 met
Paul [167]
One side of the back yard is usually the back side of the house. 
But we won't worry about that ... we'll just go ahead and fence all
four sides, like you seem to have said.

Any rectangle has two sides that are the length and two sides that are the width.
So the distance around the back yard is

           (14 + 14)  +  (12 + 12)  =   52 meters.

          (That's called the "perimeter" of the yard.)

If every meter of fence costs $9.00 , then  52 meters of fence will cost

                  (52) times ($9.00)  =   $468 .                  plus tax.
