An inequality is a statement that is of one of the four forms: 1) ax+b<0; 2) ax+b<=0; 3) ax+b>0 and 4) ax+b>=0. To solve a linear inequality such as "ax+b<0", we need to find all values of x so that ax+b<0 holds. Explain how the solution to the inequality 2x-5<25 differs from the solution to the equation 2x-

What is the best method for solving absolute value inequalities? The first most important part about solving absolute value inequalities is to understand that there are two types of inequalities. These are |ax+b|<c and |ax+b|>c. These inequalities have totally different solutions. This is because of the difference between the t
