  1. 8n-13=13-8n

              -13  -13

    8n-26= -8n

              -8n        -8n

    -26=-16n

    -16  -16 (divide)

    1.625 = n


  2. 8n-13=13-8n

    8n+8n-13=13

    16n=13+13

    16n = 26

    n = 26/16

  3. 16n = 26

    n = 26/16 = 13/8

  4. 8n-13=13-8n

    isolate the variable

    16n-13=13

    then add the 13

    16n=26

    Divide by 16

    n=1.625
