 Question 53754: I need help with solving inequalities, w+3>7w-9 as far as i seem to get (and then i get lost) is w+3>7w-9 Divide 3 by 3 and 7w-9 by 3 and then im stuck help!Answer by aaaaaaaa(138)   (Show Source): You can put this solution on YOUR website!In equations and inequalities, you only divide the entire terms by a number. Why am I telling you that? 3 or 9 aren't terms so you can divide them, w-3 and 7w-9 are. Since none of them can actually be divided by 3, we have to find another operation, specifically we'll need only addition and subtraction by now: Now we use division: Now, a catch: assume I had subtracted 7w on both sides instead of w: This isn't correct. The fact is that I've multiplied by -1/6 (dividing by -6 is the same thing as multiplying by -1/6) in the last step and, as a multiplication by a negative number, the signs must be reversed:
