python linear equation with Cramer's rule

Question

I'm new to python and attempting to write a linear equation using Cramer's Rule. I've entered the formula and have code prompting user to enter a,b,c,d,e and f but my code is getting a syntax error. I'd like to fix the code and also have a system for researching and correcting future errors.

a,b,c,d,e,f = float(input("Enter amount: ")

a*x + by = e
cx + dy = f
x = ed-bf/ad-bc
y=af-ed/ad-bc

if (ad - bc == 0)print("The equation has no solution")

else print ("x=" x, "y=" y,)

Answer 1

Basically, your code was one giant syntax error. Please read some basic tutorial, as was suggested in the comments. Hopefully this will help in the learning process (I didn't go through the actual math formulas):

a = float(input("Enter a: "))
b = float(input("Enter b: "))
c = float(input("Enter c: "))
d = float(input("Enter d: "))
e = float(input("Enter e: "))
f = float(input("Enter f: "))

##a*x + by = e
##cx + dy = f

if (a*d - b*c == 0):
    print("The equation has no solution")
else:
    x = (e*d-b*f)/(a*d-b*c)
    y = (a*f-e*d)/(a*d-b*c)

    print ("x=%s" % x, "y=%s" % y)

You have to put * between the numbers you want to multiply. You had one parenthesis missing from your input statement. The equations themselves are commented out, because otherwise Python takes them as a code (incorrectly written one). You have to enclose the denominator in parentheses because math. You have to end the if, else, elif, for, while and such with :. Indentation is VERY important in Python.
