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. WebTo satisfy this inequality will take any value positive or negative. As a result we can write the result the value of for equation (b) as: The final result from the equation (a) AND (b) will be the intersection of their value: or and find the final result for that satisfy the inequality Share Cite Follow edited Sep 30, 2013 at 8:17 user93089
