-Here our task to find the value of the equation of two variable.
Equation is f(x,y)='x+y+3'
then at x=1 and y=2, f(1,2)=6
#take input of equation and variable value
print("Enter equation of two variable in the form of x and y")
print("Enter value of x")
print("Enter value of y")
#solve equation by eval
print("Value of equation is",z)
Enter equation of two variable in the form of x and y
Enter value of x
Enter value of y
Value of equation is 18
-In this program, we take of equation of two variable and value of the variables then using eval() function we find the value of the equation.
