Hey there! :D
When a fraction is still divisible by a number, then it is not in it's simplest form.
For example, 3/6.
I know for a fact that 6/3=2 <== 3 is also divisible by itself.
3/6 (3/3=1) (6/6=1)
1/2 <== simplest form.
Try the same with 2/4.
4 is divisible by 2.
4/2= 2
2/2=1
1/2 is the simplest form.
I hope this helps!

Answer:
K+T=20
$9K + $6T = $168
K is the Kentucky blue grass in pounds
T is the Tall fescue in pounds
Step-by-step explanation:
You can start with the first equation. We don't know the exact amounts of each but we know that there was a total of 20 pounds, and there were 2 types of grass seeds, so we can get that the amount of pounds of Kentucky blue grass(K) and the pounds of Tal Fescue(T) has a sum of 20.
K + T = 20
For the second equation we know that there is a sum of $168 so we'll start with that. Then, we know he paid $9 per pound of K so $9* the value of K is the amount paid for Kentucky blue grass total. This can be represented as 9K. We do the same for T, 6T. Since the sum of the cost of $9T and $6K must be $168 we can write this as:
$9K + $6T = $168
