Solve the solution of the equation

topic:

809*??=800*??+9*?? where?? represents two digits, the result of 8*?? is two digits, and the result of 9*?? is three digits. Find the two digits represented by ?? and the result after 809*??.
That is: the solution of an equation such as 809x=800x+9x

public class funAnwser{
    
    
	public static void main (String[] args) {
    
    
		int a=809,b,i;
		for(i=10;i<13;i++){
    
    
			b=i*a ;
			if(8*i<100&&9*i>=100)
			System.out.println ("809*"+i+"="+"800*"+i+"+"+"9*"+i+"="+b);
		}
	}
}
