Sorry to ask anonymously a question but I cannot recover my account (...@...). . Why

var("x_2 z")
sol1=solve(4*x_1+ 3*x_2==z,x_2)
show(sol1)
obj1=sol1[0].substitute(z=10).rhs()
show(obj1)
plot(obj1,(x_1,0,100))

leads to 'Graphics' object is not callable ?

Apart from the fact that i have to add some var("x_1"), it works well for me.

Probably you have accidentally used plot (or solve or show) as the name of a variable in a piece of code that you didn't include here, so that the name no longer refers to the built-in function.

So don't use that name for your variable.

Thanks. I feel so stupid.

Don't worry, it happens to the best of us. You can also use from sage.plot.plot import plot to get the usual plot back in an active session. To discover that statement I used import_statements("plot").
