      To solve the equation ( x – 13 = 25 ), we can isolate ( x ) by adding 13 to both sides:

      [

      x – 13 + 13 = 25 + 13

      ]

      This simplifies to:

      [

      x = 38

      ]

      Now, let’s verify the solution by substituting ( x ) back into the original equation:

      [

      38 – 13 = 25

      ]

      Calculating the left side gives:

      [

      25 = 25

      ]

      This is true, so the correct answer is:

      A. x = 38; 38 – 13 = 25; 25 = 25
