Answer:
No, the simplification is not done correctly. When multiplying
we should get -6 instead of -9.
the correct answer is 12k-8
Step-by-step explanation:
We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.
The steps given are:

No, the simplification is not done correctly. When multiplying
we should get -6 instead of -9.
Correcting the error:

So, the correct answer is 12k-8
The two best deals would be buy two get two free and the 1/2 off because both would equal 50% off the total price of buying 4 wheels.
This is better than the alternative of only 45% off.

Your suppose to take the order pair you got and subsitute it in both of the equations. The chart has the y and x on one side and a number on the other. Treat it like an algebraic equation and try to see if when you subsitute the x and y with the order pair given you get the number on the other side of the equation. For example x + 3y = 6 once subsituted with the order pair looks like 3 + 3(1) = 6. From there you do one step at time until finally you get 6 = 6 which tells you that (3,1) is a solution for this equation. Now you have to find out if the ordered pair works for both of the equations not just one since it said "given system". Hope I explained it clearly enough :)
