first of all you need to show more clearly if the 0.1 is in the numerator or the denominator, based on the next step you took it's in the numerator, say 0.1 * 1/10y instead, or even better use parentheses so it's (1/10y)(0.1) 2x+1/100y=2x1y

1/100y=1y what you did is subtract 2x from the left side and divide the right side by 2x which uh doesn't really work

​​

y=0

'''wait how did you even get 0? no steps in between show anything'''

'''plug it in to check if it's extraneous... 0 in the denominator? try again'''

x=Identify

I think you're trying to say identity not identify

It's not a 'rational function'

what even are rational functions? how you should do it:

2x + 1/100y = 2xy

multiply both sides by 100y

200xy + 1 = 200xy^2

there are infinite solutions
