for everyone who are getting the errors, we dont need to put the apostrophes anymore so instead of solve('eqn', x) its solve(eqn, x)
hope this helps

I have an issue with matlab 2018 line 226 and line 418. Do you know what's wrong?

If you want to get result with constant c, just define it as a variable (syms x y c) but solve only for x and y.

@all, I am facing error while solving system of quadratic equations symbolically. Following the example in this video, I tried this one
>> [x, y, z]=solve('c*x-2y=1', '2*y-cz=2', 'c*z-x+y=3')
But I got the Error message like,
??? Error using ==> solve at 77
' c*x-2y=1 ' is not a valid expression or equation.

I want to know what is wrong with this...

Thank you in advance.

Both below solutions are not working. Can someone help please:
solution=(3*x-y==2, x+y==1)

solution=(3*x-y==2, x+y==1, x, y)

I believe the command "pretty" just does not do what it should...
