Perfect complements

[VanHelsing]

While sketching the indifference curve for  a perfect complement utility function, say u(x.y) = min(2x,x+y), is it necessary to equate the arguments of the function, and say that the indifference curves are Lshaped, with their vertices lying along the resulting line ? Or is there some other method to follow  ? I followed a slightly more analytical method, and the ICs I got were not L-shaped at all.Hence, my confusion. What is the actual procedure ?

I suggest you watch this video to get an understanding of how to deal with such functions.

Thank you Sir. the video cleared my confusion a lot.
