After you find the solution, how would you check to make sure your answer is correct?

Plug in your variables value.

Step-by-step explanation:

For your case, plug in -6 into the y slot

12(5+2y)= -(6-9y) +4y

12(5+2x-6)= -(6-9x-6)+4y see if that works!

To check if the solution is right you substitute.

Step-by-step explanation:

So in this case you put y = - 6

So you substitute the y as - 6

12(5+2y) = - (6-9y)+4y

12(5+ (2 times - 6)) =(6-(9 times - 6)) + (4 times - 6)

12 times (5+-12) = (6- -6) + - 24

12 times - 7 = 12+-24

-84 = - 12

And that's how to check it basically.

4 is less than 1
