Web7 jul. 2024 · The main situation where you’ll need to flip the inequality sign is when you multiply or divide both sides of an inequality by a negative number. To solve, you need to get all the x-es on the same side of the inequality. Subtract 6_x_ from both sides in order to only have x on the left. Do you flip the inequality sign when you square? WebHenry Oehlrich 3 years ago You are supposed to flip an inequality when you multiply or divide either side by a negative number.

Web24 jul. 2024 · Explanation: Consider the simplest of inequalities: a < b {a,b} ∈ R. Now consider adding or subtracting a real number, x ∈ R to the LHS. → a ± x. The only way to restore the inequality is to add or subtract x on the RHS. Thus: a +x < b + x and a −x < b − x both follow from the original inequality. Web1) Solve x + 3 < 2. The only difference between the linear equation x + 3 = 2 and this linear inequality is that I have a "less than" sign, instead of an "equals" sign. The solution method is exactly the same: subtract 3 from either side. So, in inequality notation, the solution is x < −1. Graphically (that is, on a number line), the solution ...
