# How can I get paired coordinates from the implicite function?

I have equation E^y = x. How can I use Mathematica to solve all of "y" from the desired "x" value. For example, I want to solve for "y" from x = 0.5 , 1 , 1.5 , 2 , .... , 9.5 , 10. The solution should be (x=0.5 | y= -0.693) , (x=1 | y=0) , (x=2 | y=0.693) , ..... , (x=10 | y=2.302).

PS. Solving without algebraic technique e.g. Without taking Ln at both sides. Because the real equation is quite complicated which cannot be solved. The equation above is just an example.

• Do you want to run a minimization? It's not clear why you want it done without algebraic technique. Can you please explain better the context and what you are after? By the way, welcome to Mma.SE.

• Please edit your question and explain that there. Does it take long for your equation to evaluate? Don't make us guess the information necessary to reproduce your problem. – rhermans Jul 23 '19 at 14:06
