What is Matrix?

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.

Answer 2

The number of ounces of jam that each jar can hold is 4 large jars and 2 small jars

How to solve for the variables?

The matrix is given as:

$\left[\begin{array}{cc}1&2&1&-1\end{array}\right] \left[\begin{array}{c}l&s\end{array}\right] = \left[\begin{array}{c}8&2\end{array}\right]$

Evaluate the product of the matrices

$\left[\begin{array}{c}l+ 2s&l -s\end{array}\right] = \left[\begin{array}{c}8&2\end{array}\right]$

By comparing the equations, we have:

l + 2s = 8

l - s = 2

Subtract the second equation from the first, to eliminate l

3s = 6

Divide both sides by 3

s = 2

Substitute 2 for s in l - s = 2

l - 2 = 2

Add 2 to both sides

l = 4

Hence, the number of ounces of jam that each jar can hold is 4 large jars and 2 small jars
