Answer:
Expression: 
Value of the expression when 
: 
Step-by-step explanation:
Let's first focus on the expression: '6 more than twice a number'. Twice a number is the same as saying two times a number. Let's have that number be represented by 
. Twice a number would mean 
, and 6 more than that would just be .
We'll then plug in 5 for to get the value of the expressinn:
Answer: Aiden bought 8 notebooks and 5 covers.
This is a system of equations problem. To solve this, we have to write 2 different equations and then solve them.
Our equations are:
x + y = 13
1.37x + 1.08y = 16.36
Where x is the number of notebooks and y is the number of covers.
To solve these equations, you can use anyone of these methods:
1) Graphing
2) Substitution
3) Elimination
The easiest way would be to graph them with a graphing calculator and find the point of intersection.

<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.
