    what we want to do is get the equation into the form t=...
    remember that whatever you do on the right side of the equals sign you must also do on the left side:

    .....x=t-yz .................Lets add yz to both sides
    yz+x=t-yz+yz.............The -yz+yz cancels out
    yz+x=t......................or
    .....t=x+yz
