unexpected type on a subtraction sign?

[JanieRae]

I am trying to make a program that runs through the numbers 0-100 and finds all the values that could stand in as x,y, or z in this equation:

4x + 3y - 9x = 5

Here's what i have:

/**
 * AWT Sample application
 *
 * @author: JanieRae
 * @version 1.00 10/04/20
 */
public class XYZ {
    
    public static void main(String[] args) {
        
       int x = 1;
       int y = 1;
       int z = 1;
       
        for (x=1;x<100;x++)
            {
            for (y=1;y<100;y++)
                {
             if ((4*x)+(3*y)-(9*z)=5);
                
                System.out.println("4*"+x+"+3*"+y+"-9*"+z+"=5");
             for (z=1;z<100;z++)
                  {

                   }
                }
            }
        }
    }

The only error I get is "unexpected type"
when i go to the detailed build report it says:

"unexpected type
required: variable
found : value
if ((4*x)+(3*y)-(9*z)=5);
^
1 error

Process completed."
(the arrow is underneath the subtraction sign)
but it's a subtraction sign... can someone please tell me what i'm doing wrong?

Thanks

1) Please fix your indents as bad indentation makes code hard to read and will decrease your chances of getting good help.
2) Your code is messing up on having a single = in the if boolean statement (an assignment operator) rather than a double == operator.
3) You really really don't want that semicolon after the if boolean check as it will short-circuit your code. Bad.
4) Are you sure you want the if where it's located and not within the inner z loop?

I'm sorry, I'll fix that. Thank you for the advice :)

Even after fixing what you suggested, I still get the same error =\
