Why

var("x_2 z") sol1=solve(4x_1+ 3x_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 ?

(...@...). . Why

var("x_2 z")
sol1=solve(4x_1+ 3x_2==z,x_2)
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))
plot(obj1,(x_1,0,100))
