Answer:
Infinitely many solutions.
Step-by-step explanation:
Multiply the second equation by -2, then add the equations together
(20x+2y=18)
−2(10x+y=9)
20x+2y=18
−20x−2y=−18
Add these equations to eliminate x
0=0
It is 5/16
500 and 5,000
The value of the first 5 is five hundred (500)
The value of the second is five thousand (5,000)
