-12n +7> -17
-12n> -17-7
-12n> -24 when you take out the negatives you change the > to <
12n <24
n < 24/12
n < 2

-12n+7>-17
[-7]
-12n>-24
[/-12]
but when you divide or multiply by a negative in an inequality, you must flip the sign
so...
n<2
always check your answer by picking a number such as 1 and plugging it back into the original equation
so...
-12*(1)+7>-17
-12+7>-17
-5>-17
True,
so again n<2

HeAvEnLy has it. When you get to the point where you divide both sides by -1, you need to reverse the > and make it <. Check it out. If you use 3 for n, then -36 + 7 > -17 or -29 > -17 which is not correct.

-12n+7>-17 then,
-12n>-17-7
-12n>-24 then both sides devide by -12
-12n/-12>-24/-12 so the answer will be,
n>2

n<2
-12x2=-24
-24+7=-17
therfore n must be anything less than 2 thats one of the easiest algebra problems ive ever seen.. at least since grade 5 are you a ten year old or something you should be able to do that one in your head in 10 seconds not ask ppl on the internet

Then n must be negative and less or equal than -1
