WebTo solve your inequality, you can try to form equations where both abs values are positive, and then when one is positive and the other is negative. So. 1 (Both are positive). Sign changes because 2x is always > x-5 when x is positive. 2x > x-5. x > -5. 2. (One is positive, other is negative) -2x < x-5. WebStep 1: Add 4x to both sides. −9x−4+4x<−4x+5+4x −5x−4<5 Step 2: Add 4 to both sides. −5x−4+4<5+4 −5x<9 Step 3: Divide both sides by -5. -5x/-5 < 9/-5 x > -9/5 Answer: x > -9/5 Hope that cleared some things up! :) 7 comments ( 9 votes) Upvote Downvote Flag more Show more...

WebTo solve an inequality that contains absolute value bars isolate the absolute value expression on one side of the inequality. Then, divide the inequality into two separate cases, one for each possible value of the absolute value expression, positive or negative, and solve each case separately. What does absolute value inequality mean in math? WebFeb 14, 2024 · After solving an inequality, it is often helpful to check some points to see if the solution makes sense. The graph of the solution divides the number line into three sections. Choose a value in each section and substitute it in the original inequality to see if it makes the inequality true or not. sidmouth herald e edition
