(Algebra: solve 2 × 2 linear equations) in PYTHON You can use Cramer’s rule to solve the following 2 × 2 system of linear equation: ax + by = e cx + dy = f x = (ed - bf) / (ad - bc) y = (af -ec) / (ad - bc) Write a program that prompts the user to enter a, b, c, d, e, and f and display the result. If ad - bc is 0, report that “The equation has no solution.” Sample Run 1 Enter a: 9.0 Enter b: 4.0 Enter c: 3.0 Enter d: -5.0 Enter e: -6.0 Enter f: -21.0 x is -2.0 and y is 3.0 Sample Run 2 Enter a: 1.0 Enter b: 2.0 Enter c: 2.0 Enter d: 4.0 Enter e: 4.0 Enter f: 5.0 The equation has no solution

1.) Rectangle Area The area of a rectangle is calculated according to the following formula: Area= Width * Length Design a function that accepts a rectangle's width and length as arguments and returns the rectangle's area. Use the function in a program that prompts the user to enter the rectangle's width and length, and then displays the rectangle's area.

In Python: The following equations estimate the calories burned when exercising (source): Women: Calories = ((Age x 0.074) - (Weight x 0.05741) + (Heart Rate x 0.4472) - 20.4022) x Time / 4.184 Men: Calories = ((Age x 0.2017) + (Weight x 0.09036) + (Heart Rate x 0.6309) - 55.0969) x Time / 4.184 Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for women and men. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('Men: {:.2f} calories'.format(calories_man)) Ex: If the input is: 49 155 148 60 Then the output is: Women: 580.94 calories Men: 891.47 calories
