Final answer:
The given system of equations has exactly one solution, which is x = -3/4 and y = 9/2.
Step-by-step explanation:
The given system of equations is:
2x + y = 3 ...(1)
2x - y = -6 ...(2)
To determine the type of solution, we can solve these equations using the method of elimination or substitution.
Add equations (1) and (2) to eliminate y:
(2x + y) + (2x - y) = 3 + (-6)
4x = -3
x = -3/4
Substitute this value of x into equation (1) to find y:
2(-3/4) + y = 3
-3/2 + y = 3
y = 9/2
Therefore, the system of equations has exactly one solution, which is x = -3/4 and y = 9/2.
