The system of equation that has one solution is: (d) –2x+ 7y = –5 and 2x +7y = –9
<h3>What are systems of equations?</h3>
This is a group of equations which may have none, one or more solutions.
From the list of given options, the system of equations that has one solution is:
–2x+ 7y = –5 and 2x +7y = –9
This is so because, the solution is (-1,-1)
However, the other systems have infinite many solutions

Order all the numbers:
7, 19, 21, 22, 24, 33
The 2 middle numbers are 21 and 22
Add both numbers and divide by 2:
21 + 22 = 43
43 / 2 = 21.5
The median is 21.5
