    Okay luv so let's solve this equation together:

    8n - (2n-3) = 12

    simplify

    8n+-1 (2n-3) = 12

    8n+-1 (2n) + (-1) (-3) = 12

    8n+-2n+3=12

    (8n+-2n) + (3) = 12 Combine like terms

    6n+3=12

    Then subtract from both sides

    6n+3-3=12-3

    6n=9

    Then divide both sides by 6

    6n/6=9/6

    so ... n=3/2
