WebAug 14, 2014 · I just solve the equalities without absolute values: LHS = RHS and LHS = -RHS. Then I use a number line test to check values in each interval to determine the intervals of the solution set. This led me to all values between -1 and -1/7, not including engpoints, since the original inequality was strict. Share Cite Follow http://www.mathguide.com/lessons2/AbsValue.html

WebApr 22, 2024 · Solve the compound inequality: 3 ≤ 2x + 2 < 6 Solution The first method is to write two separate inequalities: 3 ≤ 2x + 2 and 2x + 2 < 6. We solve them independently. 3 ≤ 2x + 2 and 2x + 2 < 6 1 ≤ 2x 2x < 4 1 2 ≤ x x < 2 Then, we can rewrite the solution as a compound inequality, the same way the problem began. 1 2 ≤ x < 2 WebThe steps to solve inequalities with absolute value are similar to the steps to solve equations, with the difference that we have to take into account a little extra information to solve the inequalities. The following steps are general rules that can be followed to solve these types of algebraic problems:

WebJul 23, 2014 · Edited to add: A better approach to solving the absolute value inequality is to break the problem into two cases. Case 1: If x − 1 is non-negative, then x − 1 = x − 1, and so we have the compound inequality x ≥ 1 and x − 1 ≥ 3 − x. Solve and find x ≥ 2. WebStep 1: It informs us to get the absolute value alone. The absolute value is already alone on one side. On to the next step... Step 2: It tells us to change the inequality to an equality. …

WebThe easiest way to do this is to turn the one equation into two equations. Absolute values have the effect of changing what is inside the symbols into a positive number if they weren't already, so we have to consider the case where they were already positive, and the case where what's inside the symbol was negative to begin with. WebAn absolute value equation is an equation that contains an absolute value expression. The equation x = a Has two solutions x = a and x = -a because both numbers are at the distance a from 0. To solve an absolute value equation as x + 7 = 14 You begin by making it into two separate equations and then solving them separately. x + 7 = 14
