Edit: I have solved my problem with rhs.
Hi,
I have created a symbolic equation via isolate command. Resulting equation is:
x1_dot == (1570*u)/41 - x3*x2_dot - (3060*x1)/(41*x3) - (6426*x2)/(1025*x3)
%Should be: x1_dot = (1570*u)/41 - x3*x2_dot - (3060*x1)/(41*x3) - (6426*x2)/(1025*x3)
I should remove logical equality to continue my work. How can i make this?
Thanks,

Actually, i asked the question uncorrect; i'm sorry.
I have defined an equation as eqn_1 and arranged it according to x1_dot via isolate command.
x1_dot=isolate(eqn_1,x1_dot)
I am using x1_dot in next steps. When i write x1_dot at command window, the result contains ==. This two equality symbol make my code wrong.
I wish, it may be clear. :)

Haha i did it:
It seems very easy :))
x1_dot=rhs(isolate(eqn_1,x1_dot));

syms x1_dot u x2_dot x1 x2 x3
x1_dot = (1570*u)/41 - x3*x2_dot - (3060*x1)/(41*x3) - (6426*x2)/(1025*x3)
x1_dot =

How can you get result as png format?

I don't think there is option of saving as image.....you can try in Live editor...and try to print the variable...it should be printed as shown in the answer...then you can save it as image I guess. Or there might be any other way which I am mot aware.
