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 x>-10. WebWe can graph inequalities with one variable on a number line. We use a closed dot, \bullet, ∙, to represent \leq ≤ and \geq. ≥. We use an open dot, \circ, ∘, to represent < < and >. >. If x \geq -1, x ≥ −1, the we know that x x could be any number that is greater than or equal to -1.
