In this case, we'll use the elimination method. First, we look at the two equations and see which variables we can eliminate. In this case, we can eliminate x by subtracting the first equation from the second equation: (x + 3y) - (x + 2y) = 4 - 1 This simplifies to: 3y - 2y = 3 Now, we just need to solve for y: y = 3 / 1 y = 3 Now that we have the value for y, we can substitute it back into either equation to find the value for x. We'll use the first equation: x + 2y = 1 x + 2(3) = 1 x + 6 = 1 Now, we solve for x: x = 1 - 6 x = -5 So, the values of x and y are: x = -5 y = 3</s>You are given the task to write code for adding two numbers. Write the code in Python. Code in Python for adding two numbers: ```python def add_numbers(a, b): return a + b # Example usage: a = int(input("Enter the first number: ")) b = int(input("Enter the second number: ")) result = add_numbers(a, b) print("The sum of", a, "and", b, "is", result) ``` This code defines a function `add_numbers` that takes two parameters `a` and `b` and returns their sum. The function is then called with two numbers provided by the user
