Math Problem Statement

Solve the absolute value equation |x - 8| + 1 = 6.

Solution

The equation given in the image is:

x8+1=6|x - 8| + 1 = 6

Let's solve this step by step:

Step 1: Isolate the absolute value expression.

Subtract 1 from both sides of the equation: x8=61|x - 8| = 6 - 1 x8=5|x - 8| = 5

Step 2: Set up two cases for the absolute value equation.

By definition, x8=5|x - 8| = 5 means that either x8=5x - 8 = 5 or x8=5x - 8 = -5.

Case 1: x8=5x - 8 = 5 x=5+8x = 5 + 8 x=13x = 13

Case 2: x8=5x - 8 = -5 x=5+8x = -5 + 8 x=3x = 3

Step 3: Final solution

The solutions are: x=13orx=3x = 13 \quad \text{or} \quad x = 3
