Here is a set of practice problems to accompany the Absolute Value Equations section of the Solving Equations and Inequalities chapter of the notes for Paul Dawkins Algebra course at Lamar University. Section 1.4 Solving Absolute Value Equations 31 Identifying Special Solutions When you solve an absolute value equation, it is possible for a solution to be extraneous.An extraneous solution is an apparent solution that must be rejected because it does not satisfy the original equation. Now subtracting 8 from both sides x + 8 - 8 = 16 - 8. Solve equations like 3|x+1| + 7 = 6|x+1| + 6. $ึ�'+รg�๓4 They are the same distance from 0 on the number line, but in opposite directions. There is yet another rule that you must remember when solving absolute value equations. How to solve an absolute value function. For example, the absolute value of -2 is 2, and the absolute value of 2 is also 2. The equation $$\left | x \right |=a$$ Has two solutions x = a and x = -a because both numbers are at the distance a from 0. If one solution enter the answer in both fields.If no solution, enter DNE in both fields. Type in any equation to get the solution, steps and graph This website … Next lesson. Now subtracting 8 from both sides, we get x + 8 - 8 = -16 - 8, x= -24. If you're seeing this message, it means we're having trouble loading external resources on our website.
