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
-11y = -13x -12
then i got -11y=-25

-13x does not comdine with -12....they are two seperate entities that dont mix
if you have 13 apples and 12 oranges; how many apples do you have?
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)
the / sign means divide right?

and you get some random mixed up number?
yes... '/' means divide and you get a decimaled number if you want to go that route
