I think there is more to the question, but the equation to solve for the number of months until Rita has enough money to put a down payment for a condominium is 15,000=8,000+850X

9(2w−y)=21w−9y

First you multiply the numbers in the parenthesis by 9

$18w-9y=21w-9y$

subtract. 21w-18w=3w

$-9y=3w-9y$

add. -9y+9y=0

$0=3w$

divide.

$0=w$

Final answer is 0.
