Assign a variable solve equation with a function expression that has three parameters (x, y, and z) and returns the result of evaluating the expression z-y+2*x

Following is a python code

def solveEquation(x,y,z):

   res=z-y+(2*x)  #stores expression's value

   return res

solveEquation(2,1,4)  #calls function

OUTPUT :

7

Explanation:

In the above code solveEquation is the function which takes three arguments x,y and z and their type is decided while calling the function and passing the values to these arguments. After the values are passed, an equation is written which is solved and the result is stored in variable res and then that variable's value is returned.
