1. The problem statement, all variables and given/known data y=(2-x)/(5x) Solving for x=f(y) I can get as far as 5xy=(2-x) Tried 5xy=-1(x+2) All attempts at solving this have given me the wrong answer, and I end up with x on both sides of the equation. Stuck and not sure what to do. Correct answer is x=2/(5y+1) , but I don't know how to get there. Thanks for any help!
