Answer: 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.
