Forming and solving inequalities
WebSolving Inequalities. Don’t worry if you get a question wrong! Forgetting is an important step in learning. We will recap next lesson. Q1. What is the solution to the following inequality: x - 4 ≤ 10. Q2. What is the solution to the following inequality: 3x + 4 > 10. 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.

WebFirst step: Factor out the inequality. (what times what equals 15 and when added together makes 8?) (x+3) (x+5)<0 Step 2: Solve for x. This inequality has two answers. X can either be -3 or -5, since both, when plugged in for x, will make the inequality equal to zero.
WebIn math, inequality represents the relative size or order of two values. How do you solve inequalities? To solve inequalities, isolate the variable on one side of the inequality, If you multiply or divide both sides by a negative number, flip the direction of the inequality.
