How can you solve real world mathematical problems using two linear equations in two variables

import numpy as np

a = int(input ("Enter a"))

b = int(input ("Enter b"))

c = int(input ("Enter c"))

d = int(input ("Enter d"))

c1 = int(input ("Enter c1"))

c2 = int(input ("Enter c2"))

array1 =[[a, b],[c, d]]

A = np.array (array1)

B = np.array ([c1, c2])

X = np.linalg.inv (A).dot (B)

print (X)

Explanation:

let ax + by =c1

     cx + dy =c2

We have used the above NumPy library that has the methods for matrix calculation, and here we have used matrix multiplication, and the inverse of a matrix to find the value of x and y.

We know AX=B

X = inv A. B

And this we have used above. We can calculate inv A and do matrix multiplication using NumPy. And thus we get the above solution.
