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.
Log 3 is the correct answer
<u>Given:</u>
It is given that the value of the graph when the input 7 is 
We need to determine the value of x when 
<u>Value of x when </u>
<u>:</u>
The value of x can be determined by using the graph.
From the graph, we need to determine the value of x when
other than the value x = 7.
This can be determined by finding the point at which the line meets the point y = 4, we can find the corresponding x - value.
Thus, from the graph, it is obvious that the graph also meets the point y = 4 when x = -8.
Therefore, the input value is x = -8 which makes 
Hence, the input value other than 7 for which
is x = -8.
