Code:
import java.util.Scanner;
public class Matrix_Representation_Equations
{
public static void main(String args[])
{
char []var = {'x', 'y', 'z', 'w', 'a', 'b', 'c', 'd', 'e'};
System.out.println("Enter the number of variables in the equations: ");
Scanner input = new Scanner(System.in);
int n = input.nextInt();
System.out.println("Enter the coefficients of each variable for each equations");
System.out.println("ax + by + cz + ... = d");
int [][]mat = new int[n][n];
int [][]constants = new int[n][1];

{
for(int j=0; j
{
mat[i][j] = input.nextInt();
}
constants[i][0] = input.nextInt();
}
System.out.println("Matrix representation is: ");
for(int i=0; i

}
System.out.print(" "+ var[i]);
System.out.print(" = "+ constants[i][0]);
System.out.println();
}
input.close();
}
}
Output:
Enter the number of variables in the equations:
3
Enter the coefficients of each variable for each equations:
ax + by + cz + ... = d
1 2 3 4
5 6 7 8
9 0 1 2
Matrix representation is:
1 2 3 x = 4
5 6 7 y = 8
9 0 1 z = 2
