    you dropped the 13x off somewhere and unbalanced your equation

    13x -11y = -12 ; -13x to both sides to keep it equal

    13x-13x -11y = -12 - 13x

    13 apples so i divide -11 to both sides to get y alone?

    yes... (-11/-11)y = -13x/-11 -12/-11 y = (13/11)x + (12/11)

    yes... '/' means divide and you get a decimaled number if you want to go that route
