WebWhen solving inequalities, like, say, this one: -2x+5<25. You would cancel out the +5 with -5 and subtract 25 by 5, so you're left with this: -2x<20. But now, since you're dividing by -2 (remember that multiplying or dividing by a negative number will reverse the sign) it will no longer be less than, it will be greater than: -2x/-2>20/-2. WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3.
