Answer:
-11/2
Step-by-step explanation:
Put the numbers into the expression and do the arithmetic.

The factors of 15 are 1, 3, 5 and 15. Now, as 1 is neither prime and nor a composite number (1 is not Prime because for a number to be a prime, it should have exact 2 factors i.e. 1 and itself, but 1 has only one factor. Therefore 1 is not prime.)
So the smallest prime factor of 15 is 3.

<h3>What is Matrix?</h3>
A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
Here, from the given matrix by comparing the equations, we have:
l + 2s = 8 ...........(i)
l - s = 2 .............(ii)
Subtract the second equation from the first, to eliminate l
3s = 6
s = 2
Substitute 2 for s in l - s = 2
l - 2 = 2
Add 2 to both sides
l = 4
Thus, the number of ounces of jam that each jar can hold is 4 large jars and 2 small jars.
