simplify
OpenStudy (anonymous):
y = the same thing so they cancel out. then ur left with 7>5. get it?
OpenStudy (anonymous):
acyuly, y=y so that's why they cancel out
OpenStudy (anonymous):
is there a way that "y" could be included in my answer?
OpenStudy (anonymous):
i have spelling errors, actualy

no
OpenStudy (anonymous):
for example : 2(4-n)<3n-7 = n>3
OpenStudy (anonymous):
in this case, yes because in your first question, the y's canceled out
OpenStudy (anonymous):
7-y>5-y
=7>5-y+y. the y's cancel out
OpenStudy (anonymous):
replace y with any #

why wouldn't you do something like, " 7 - y > 5 - y = 7 + 5 - y > 5 + 5, then the 5's would cancel each other out?
then eventually the y's become 2y
OpenStudy (anonymous):
where did u get the extra 2 five's?
OpenStudy (anonymous):
u r missing a y
OpenStudy (anonymous):
it's solving inequalities
and yes - i forgot to add another y
OpenStudy (anonymous):
u can't have more fives

you would add 5 to both sides, just to show your work, but you took it and added y to both sides, which you're sure is correct?
OpenStudy (anonymous):
the y's just cancel out without doing much work
OpenStudy (anonymous):
is this logically correct then?
OpenStudy (anonymous):
which answer? mine or yours?
OpenStudy (anonymous):
\[-5(k-1)\ge5(2-k)\] solve this one

it'll take me some time
OpenStudy (anonymous):
isolate the k's to see if they cancel out
OpenStudy (anonymous):
\[1\ge2\]
there is no solution
OpenStudy (anonymous):
thnx : )
