your missing some number to do the process
the first question you add all the sides
If you multiply (1/4)* 84 you get 21 so your awnser is 21
Division because if you divide the two functions together, you keep the 3 in the x term. If you add the two functions, your coefficient is 6. If you subtract, the x term is eliminated. If you multiply, you'll get 9x.
3 is smaller than 6 or 9 :)
