2x-4y=6 is your answer
It much form y=mx+b
To simplify 12/18, you can see that the greatest common factor is 6 (6 × 2 = 12, 3 × 6 = 18), and so you can divide by 6 to get D. 2/3 as your answer.
I'm pretty sure you could just select the answer to not show your working :)
I hope this helps!
About 285 should go into each box
All you have to do is divide 5135 by 18
Y > 2x *greater than or equal to, can't do the equal to on the computer)
30 < x + y < 50 *also equal to*
