Example: Absolute Value Equations with No Solution

If isolating the absolute value expression results in an equation where the absolute value equals a negative number, the equation possesses no solution. For example, to solve 23x4+11=3|\frac{2}{3}x - 4| + 11 = 3, isolating the absolute value by subtracting 1111 from both sides yields 23x4=8|\frac{2}{3}x - 4| = -8. Because the distance represented by an absolute value can never be negative, this statement is mathematically false for any value of xx. Thus, finding it equal to a negative constant immediately indicates that there is no solution.
