Answer:
<em>The programming language is not stated;</em>
<em>However, the program written in Python is as follows</em>
def solveEquation(x,y,z):
result = z - y + 2 * x
print(result)
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
print(solveEquation(x,y,z))
Explanation:
This line defines the function solveEquation
def solveEquation(x,y,z):
This line calculates the expression in the question
result = z - y + 2 * x
This line returns the result of the above expression
print(result)
The next three lines prompts user for x, y and z
x = float(input("x = "))
y = float(input("y = "))
z = float(input("z = "))
This line prints the result of the expression
print(solveEquation(x,y,z))
