-Here our task to find the value of the equation of three variable.
Equation is f(x,y,z)='x+y+z+4'
then at x=1,y=2 and z=3, f(1,2,3)=10
#take input of equation and variables value
print("Enter equation of three variable in the form of x,y and z")
print("Enter value of x")
print("Enter value of y")
print("Enter value of z")
#solve equation by eval
print("Value of equation is",ans)
Enter equation of three variable in the form of x,y and z
Enter value of x
Enter value of y
Enter value of z
Value of equation is 13
-In this program, we take of equation of three variable and value of the variables then using eval() function we find the value of the equation.
