Yeah you were so close to the right answer, the right answer is 86 elephants + 20 aliens = 685765,58,6846549588558556996566 hectares of weed farming + Justin Bieber = 0
You beat me to it. The density of water is 1. Duh. The density of salt water will be something like 1.02 to 1.04. Boring-ass teachers with too-easy test questions.
That makes 14+x=18, which turns into x+14 and that's impossible cause the polynomial is not factorable with rational numbers, thus making the density of the atlantic ocean unsolvable due to x+14 being unsolvable. MATH BICHES
Actually X is 4. As explained with my math up there^. You have to get rid of the 14. So you must subtract 14 from each side. (14-14)+X=(18-14) Which leads to X=4.
