# Solve three variable equation in python by R4R Team

-Here our task to find the value of the equation of three variable.

Example-
Equation is f(x,y,z)='x+y+z+4'
then at x=1,y=2 and z=3, f(1,2,3)=10

program-

#take input of equation and variables value
print("Enter equation of three variable in the form of x,y and z")
equation=input()
print("Enter value of x")
x=int(input())
print("Enter value of y")
y=int(input())
print("Enter value of z")
z=int(input())

#solve equation by eval
ans=eval(equation)
print("Value of equation is",ans)

output-

Enter equation of three variable in the form of x,y and z
x+2*y+z*3+7
Enter value of x
1
Enter value of y
1
Enter value of z
1
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.
