    very good; now what do you think should do first to get this to look like that?

    yes... lets "move" the -3x over by adding +3x to each side: 2y = 3x+8 now what can we do?

    yes.. we can do that by "dividing" both sides by 2 right? will that help us?

    yes so . 2y = 3x + 8 y = 3x + 4 ?

    very close.... I see you divided 8 by 2 = 3; but we also need to divide 3x by 2...the number gets us a fraction. y = (3/2)x + 4 do you see that?

    you are :) does y = (3/2)x + 4 look like: y = mx + b?
