Lily_Grace Posted September 26, 2012 Share Posted September 26, 2012 I need to see if we're wrong or the book is wrong. :D I added the parentheses to keep the fractions straight, but it's exactly as written otherwise. Oh, and show your work. ;) 2 - y + 10 + (y/2) = 3y - (7/3) + 2y Quote Link to comment Share on other sites More sharing options...
Arcadia Posted September 26, 2012 Share Posted September 26, 2012 2 - y + 10 + (y/2) = 3y - (7/3) + 2y 12 - (y/2) = 5y - (7/3) 12 + (7/3) = 5y + (y/2) 43/3 = (11/2)y y = (43/3)/(11/2) y = (43/3) * (2/11) Y = 86/33 Y = 2 (20/33) Quote Link to comment Share on other sites More sharing options...
Lily_Grace Posted September 26, 2012 Author Share Posted September 26, 2012 Okay, where did your first y go? That's where we're lost. Quote Link to comment Share on other sites More sharing options...

Arcadia Posted September 26, 2012 Share Posted September 26, 2012 Left Hand Side 2 - y + 10 + (y/2) = 2 + 10 - y + (y/2) = 12 - (y/2) Right hand side 3y - (7/3) + 2y = 3y + 2y - (7/3) = 5y - (7/3) LHS = RHS 12 - (y/2) = 5y - (7/3) ETA: saw that you solved it while I was typing :) Quote Link to comment Share on other sites More sharing options...
