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. WebOct 6, 2024 · Interval notation: ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 2.7.4.
