Answer:
y≤-3x-6
Explaination:
First you distribute the -3 to the x and -6.
So you would then have y-6≤-3x-12.
Then you would add 6 to each side.
After doing this you will have y≤-3x-12+6.
Then you combine like terms which are -12 and 6 to get -6. Then you are left with your final answer of y≤-3x-6.
I hope this helped :) (I believe I did it correctly based off of my knowlege)
