WebTo solve , divide both sides by. Now, let’s solve the other inequality. Let’s start off by adding on both sides. To solve for , we’ll divide both sides by . So, now we graph this by drawing a number line. Draw an open circle at since it’s not equal to. Then draw a line going to the right since is greater than . WebSolving inequalities. Do excercises Show all 3 exercises. Solving inequalities I. Solving inequalities II. Solving inequalities III. When we add or subtract the same number on both sides of the truth of the inequality doesn't change. This holds true for all numbers: x > y → x < y →. x + z > y + z → x + z < y + z →. WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction. Example: Alex has more money than Billy, and so Alex is ahead. describe the big five personality dimensions
