    now you need to set up a system of equations to solve

    basically if you have two variables, you need two equations to work with to solve for the variables

    now that you have n+u=18 and n=1/5 * u, you want to substitute n back into the first equation so you have only 1 variable to work with

    would it be 1/5 * u+u=18 or 2u=18-1/5 or something like that
