SciPy - Linear Algebra (scipy.linalg)

What will be the output of this code?

import numpy as np
from scipy.linalg import solve
A = np.array([[1, 2], [3, 4]])
b = np.array([5, 11])
x = solve(A, b)
print(x)

A[2. 1.]

B[3. 4.]

C[1. 2.]

D[4. 3.]

Step-by-Step Solution

Solution:

Step 1: Write the system of equations
1*x1 + 2*x2 = 5 and 3*x1 + 4*x2 = 11.
Step 2: Solve the system
From first: x1 = 5 - 2*x2. Substitute in second: 3*(5 - 2*x2) + 4*x2 = 11 -> 15 - 6*x2 + 4*x2 = 11 -> -2*x2 = -4 -> x2 = 2, then x1 = 5 - 4 = 1.
Final Answer:
[1. 2.] -> Option C
Quick Check:
Solution vector x = [1, 2] [OK]

Quick Trick: Substitute and solve stepwise for x [OK]
