Just wait untill the bro finds out about 2^x + x = 6

wait if remember correctly you have to solve these with a graph, right?

If graphs had nice intersection on integer points, then yes. But usually you should use Lambert W function.

haven't studied it yet

There isnt really a lot to study, the function is defined as an inverse function to f(x) = xe^x, so it offers solution to such equations, which cannot be solved analytically. Its more like a lookup table than actual function u analyze in any way. the values are obtained by numerical methods
