8+16=24
Answer: (5,2)
Step-by-step explanation:
Given equations: 
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get

Adding equation (3) and (4), we get

Substitute x=5 in equation (4), we get

Hence, the solution of the both equations is (5,2).
I believe the answer is D. $34.43

<em>Translate into an algebraic equation:-</em>
<em>The quotient of a number and 5.</em>

✳︎ First, the word "quotient" indicates that we divide.
Here, we have the quotient of a number and 5, so we divide the number by 5; let the number be d.
So the quotient of d and 5 looks as follows:-

<h3>Good luck with your studies.</h3>

None of them have a solution of x, but 5x=15, 7x-2=19, and 5x+6=21 all have the same answer of x=3
