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. We show this solution on a number line by placing ... WebWe can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra ), like this: Example: x + 3 < 7 If we subtract 3 from both sides, we get: x + 3 − 3 < 7 − 3 x < 4 And that is our solution: x < 4 In other words, x can be any value less than 4.
