Answer 2

yes

Answer 3

it's basic i know, but it's been a while since pre-calc

Answer 4

get common denominator of yz^3

\[\rightarrow \frac{xz^{3}}{yz^{3}} +\frac{2y}{yz^{3}} = \frac{xz^{3}+2y}{yz^{3}}\]

Answer 5

so you just multiply both sides by z^3?

Answer 6

Was the question only that much? If it was then its basic LCM type!!

Answer 7

Yeah i feel really stupid but i can't remember how to get the least common denominator. haha
