Answer to Question #262377 in Python for Kelly

Question

You can use Cramer’s rule to solve the following 2 x 2 system of linear equations: Ax+By=E

Cx+Dy=f

X=ED-Bf/AD-Bc

Y= Af-Ec/AD-Bc

Write a program that prompts the user to enter A, B, C, D, E, and F nd display the

result. If AD – BC is 0, report that “The equation has no solution”.

Do all you can to make your program structure when running, conform with the sample runs

given below:

Enter a, b, c, d, e, f: 9.0, 4.0, 3.0, -5.0, -6.0, -21.0

x is -2.0 and y is 3.0

Enter a, b, c, d, e, f: 1.0, 2.0, 2.0, 4.0, 4.0, 5.0

The equation has no solution

Answer 1

a,b,c,d,e,f = [float(i) for i in input("Enter a, b, c, d, e, f: ").split(',')]
diff = a*d-b*c
if diff!=0:
    x=(e*d-b*f)/diff
    y=(a*f-e*c)/diff
    print(f"x is {x} and y is {y}")
else:
    print("The equation has no solution")
