Answer:
Only one solution ![x=\frac{5}{4},y=0](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%7D%7B4%7D%2Cy%3D0)
Step-by-step explanation:
![4x-5y=5..............(1)\\0.08x+0.10y=0.10...........(2)](https://tex.z-dn.net/?f=4x-5y%3D5..............%281%29%5C%5C0.08x%2B0.10y%3D0.10...........%282%29)
Multiply equation
by ![50](https://tex.z-dn.net/?f=50)
![4x-5y=5........(3)](https://tex.z-dn.net/?f=4x-5y%3D5........%283%29)
Now from equation ![(1)](https://tex.z-dn.net/?f=%281%29)
equation![(3)](https://tex.z-dn.net/?f=%283%29)
![8x=10\\x=\frac{10}{8}\\x=\frac{5}{4}](https://tex.z-dn.net/?f=8x%3D10%5C%5Cx%3D%5Cfrac%7B10%7D%7B8%7D%5C%5Cx%3D%5Cfrac%7B5%7D%7B4%7D)
Put the value in equation ![(1)](https://tex.z-dn.net/?f=%281%29)
![5-5y=5\\5y=0\\y=0](https://tex.z-dn.net/?f=5-5y%3D5%5C%5C5y%3D0%5C%5Cy%3D0)
hence only one solution exists
