The answer to this equation is y = -1/3.
Steps:
y + 8/9 = 5/9
Subtract 8/9 from both sides.
y + 8/9 - 8/9 = 5/9 - 8/9
Then you get your answer, which is y = -1/3
Well, if each cake takes 2.5 cups, all you need to do is multiply 2.5 x 9 to get your answer!
(100+3-4(4-5))/(6+5+5+5+300)
=(100+3-16+20)/(321)
=(107)/(321)
=1/3
Hope it helps : )
