In the given image, a_{23} is 5. The correct option is the first option 5

<h3>Matrix notation</h3>

From the question, we are to determine which entry in the given matrix represents a_{23}

NOTE: For any entry denoted as a_{mn}, it represents the entry in the <em>m</em>-th row and <em>n</em>-th column.

Thus,  

 a_{23} represents the entry in the 2nd row and 3rd column.

In the given image, the entry in the 2nd row and 3rd column is 5.

Hence, in the given image, a_{23} is 5. The correct option is the first option 5

Combine 2y+1x=40 and y=2x using substitution
fomenos

2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution

<em><u>Solution:</u></em>

Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method

The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.

<em><u>Given equations are:</u></em>

2y + 1x = 40 -------- eqn 1

y = 2x ----------- eqn 2

We can substitute eqn 2 in eqn 1

Which means, substitute y = 2x in place of y in eqn 1

2(2x) + 1x = 40

4x + 1x = 40

5x = 40

x = 8

From eqn 2,

y = 2(8)

y = 16

Thus by combining using substitution method we found the solution
