solve the inequality..
-35 < 6x + 7 < 1
Your answer is between those 2 answers
so everything between -7 (-7 not included) and infinity is a possible answer
so everything between -1 and - infinity is a possible answer here
making the final answer between -7 and -1 (both not included)... (I totally forgot how to put this mathematically )
Edit: something like this... [-7,-1](I think? )
if we try to divide each term by a variable it won't work because we do not know the sign.
i followed an example out of text book which was a similiar problem
we both have the same answers
consider multiple replies to the same post a good thing...
