1.
c=cows
b=chicens
c+b=28
chicen has 2 legs
cow has 4 legs
4c+2b=64
c+b=28
4c+2b=64
multiply first equaiton by -2 and add to second
-2c-2b=-56
4c+2b=64 +
2c+0b=8
2c=8
divide 2
c=4
sub
c+b=28
4+b=28
minus 4
b=24
4 cows and 24 chicens
2.
t=twelve oz
s=sixteen oz
t+s=20
12t+16s=300
find t
multiply first equation by -16
-16t-16s=-320
add to first equation
-16t-16s=-320
12t+16s=300 +
-4t+0s=-20
-4t=-20
divide -4
t=5
five 12 oz bottles
1. 4 cows, 24 chicen
2. 5 twelve oz bottles

Hope this helps!!
If I am wrong, please tell me, I enjoy learning from my mistakes:)
(5 + 4) / ( 8 + 4) = 9/12 = 3/4
3/4 - 5/8 = 6/8 - 5/8 = 1/8 <== this much the fraction has changed.
