Answer:
Infinite number of solutions
No unique solution
Step-by-step explanation:
5x - 2y = 10 (1)
y = 5/2x - 5 (2)
Multiply (2) by 2 to get
2y = 5x - 10
Rewrite the above equation as 5x - 2y = 10 (3)
Since both equations are the same, we are provided with a single equation in 2 variables there are infinite solutions
