OOP Program-2

(2) Write a program that solves the following equation and displays the value x and y:

1) 3.4x+50.2y=44.5        2) 2.1x+.55y=5.9 

(Assume Cramer’s rule to solve equation  

ax+by=e    x=ed-bf/ad-bc

cx+dy=f     y=af-ec/ad-bc )

Program code:

import java.util.Scanner;

public class OOP_02

{

public static void main(String[] args) 

 {

         Scanner input = new Scanner(System.in);

  System.out.println("Values from Equestion - 1 :");

  System.out.print("Enter value of a : ");

  double a = input.nextDouble();

  System.out.print("Enter value of b : ");

  double b = input.nextDouble();

  System.out.print("Enter value of e : ");

  double e = input.nextDouble();

  

  System.out.println("Values from Equestion - 2 :");

  System.out.print("Enter value of c : ");

  double c = input.nextDouble();

  System.out.print("Enter value of d : ");

  double d = input.nextDouble();

  System.out.print("Enter value of f : ");

  double f = input.nextDouble();

  double x = ((e*d)-(b*f))/((a*d)-(b*c));

  double y = ((a*f)-(e*c))/((a*d)-(b*c));

  System.out.print(" X = "+ x + " Y = " + y);

  

 }

}

Output:
