Factors of -6 that add up to -1:
(x - 3)(x + 2)
Set them to 0 and solve for x
<span>x = 3 </span>
<span>x = -2</span>
(X-4)-(y+5)=5.4 value of f(3)
X + Y = 18
X=chickens, Y=Cows
2x + 4y = 60
Let's try 8 and 10.
16 + 40=56, no, 32+20=52, no. 8&10 do not work.
Let's try 9 and 9.
18+36=54, no. 9&9 do not work.
Let's try 11 & 7.
22+28=50, no. 14+44=58, no.
Let's try 12 & 6.
24+24=48, no. 12+48=60 YES!
There are 12 cows and 6 chickens.
2/3 * 9/20 = 18/60
= 9/30
= 3/10
