This is for INTRODUCTION TO Java
Design a class named LinearEquation for a 2 times 2 system of linear equations: ax + by = e cx + dy = f x = ed - bf/ad - bc y = af - ec/ad - bc The class contains: Private data fields a, b, c, d, e and f. A constructor with the arguments for a, b. c, d, e and f. Six getter methods for a, b, c, d, e and f. A method named issolvable() that returns true if ad - bc is not 0. Methods getX() and getY() that return the solution for the equation. Draw the UML diagram for the class and then implement the class. Write a test program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that \"The equation has no solution.\" See Programming Exercise 3.3 for sample runs.Solution
Hi Friend, Please find my implementation.
Please let me know in case of any issue.
