I would like to explain a bit of how the program works.

**How it Works**

First, the program request for inputs a1, a2 and a3, those are the coefficient of the first equation. Then it prompts for the coefficients: b1, b2 and b3, the coefficients of the second equation.

It then solves and display the result for x1 and x2

**Source code:**

#CATEGORY: PYTHON TUTORIALS

print(“n*** PROGRAM TO SOLVE 2×2 SIMULTANEOUS EQUATIONnn”)

print “nEquation of the form a1x + b1y = c1, a2x + b2y = c2 nnn”

#INPUT THE COEFFICIENTS OF EQUATION 1

a1 = input(“nEnter a1: “)

b1 = input(“nEnter b1: “)

c1 = input(“nEnter c1: “)

#INPUT THE COEFFICIENTS OF EQUATION 2

a2 = input(“nEnter a2: “)

b2 = input(“nEnter b2: “)

c2 = input(“nEnter c2: “)

#USING CRAMER’S RULE…

D = (a1 * b2) – (a2 * b1)

Dx = (c1 * b2) – (c2 * b1)

Dy = (a1 * c2) – (a2 * c1)

x = Dx/D

y = Dy/D

#DISPLAY THE RESULTS

print “*********The results are:******************* nn”

print “x = {}”.format(x)

print “y = {}”.format(y)

raw_input(“nnPress <Enter> to exit…”)
