    remember that | | these 2 lines mean absolute value, so if its negative you take it to bne positive, and if its positive you leave it to be positive

    okay so |X| is very similiar but you take all the negative part and make that positive

    now we simplfied our equation earlier with |x-2|+10-10=12-10 |x-2|=2 so we want to see where our value is 2 on the graph

    maybe a much simpler way to go about that is |x-2|=2 now you know that if you get a -2 in the abs value it will be 2 and 2 in the abs value is 2 so we have to solve x-2=-2 and x-2=2 these 2 equations
