3x+4y=12
13-(2c+2)>= 2(c+2)+3c
13-2c-2>=5c+4
11>=7c+4(((((this varies from yours, from here onward))))
7>=7c
c is less than or equal to 1
How did you get the 7 > 7c?
If you follow my work, you get it. I subtracted 2 from 13 to get 11, then subtacted 4 from both sides.
Thank you! I don't know why I didn't see that.
