Ok. another algebra question…?
here the correct question:
8 – l 1 – y l = 7
[then of course the other problem would be:]
8 – l 1 – y l = -7
so ya. i know u add -8 to both sides, then you get…wat,
– l 1 + -y l = -7 ???
(sry my teacher taught us to always add the opposites, ex-
5 – 7 = 5 + -7…….its a habit)
Favorite Answer
so you subtract 8 from both sides and get
– l 1 – y l = -1
then you divide both sides by -1 and get
l 1 – y l = 1
then you set up the 2 equations
1-y = 1…and…1-y = -1
so then the answers would be
y = 0 and y = 2
there should be 2 problems like this one w/ negative answer and the other w/ positve
8-1-y= -7 or 8-1-y=7
then you combine like terms in this case subtract 8 -1 u end up with this
7- y = -7 or 7-y = 7
subtract 7 from both sides to get y=
-y = -14 or -y = 0
then divide by -1 and these are you answers
y = 14 or y = 0
