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

<span>A.(0,8)
B.(-1,8)
C.(1.5,10)
D.(2,16)
Simply substitute the value of x to get the value of y.
y = 8x
(0,8) y = 8(0) ; y = 0
(-1,8) y = 8(-1) ; y = -8
(1.5,10) y = 8(1.5) ; y = 12
(2,16) y = 8(2) ; y = 16
The correct ordered pair is D. (2,16)</span>
