Answer:
Equation is
and when y=2 and z=4, x will be 4.
Step-by-step explanation:
Given:
x varies jointly with y and z.
It also means x is directly proportional to y and z.

From above values we can compute the equation as.

Hence the Equation is 
Now y=2 and z=4 we get.

Hence when y=2 and z=4, x will be 4.

<h3>What is a program in coding?</h3>
Program or programming is the combination of codes. These codes are used to generate the program such that a machine can understand the inputs given to it.
The program is written to allow a user to guess a number. This number should be between the number 0 to 10.
Here, the input is needed to a machine or computer, for which it's process the number and show if the guessed number is correct or not.
Hence, the completed code to generate and save a number in the program which allow a user to guess a number from (1,10) is input.
