Math Problem Statement

|x - 2| + 5 = 9

Solution

The equation shown in the image is:

x2+5=9|x - 2| + 5 = 9

To solve this, let's follow these steps:

Step 1: Isolate the absolute value

First, subtract 5 from both sides of the equation:

x2=95|x - 2| = 9 - 5 x2=4|x - 2| = 4

Step 2: Solve the absolute value equation

Now that we have x2=4|x - 2| = 4, this means:

  1. x2=4x - 2 = 4
  2. x2=4x - 2 = -4

Step 3: Solve both equations

For x2=4x - 2 = 4: x=4+2=6x = 4 + 2 = 6

For x2=4x - 2 = -4: x=4+2=2x = -4 + 2 = -2

Final Answer:

The solutions are: x=6orx=2x = 6 \quad \text{or} \quad x = -2
