Best ResponseYou've already chosen the best response.1"switch" y and x and solve for y so, if the original function is y = 3x  8.7, you switch y and x to get x = 3y  8.7 solve again for y

Best ResponseYou've already chosen the best response.1sure, so we have: x = 3y  8.7 what do you get when you add 8.7 to both sides?

Best ResponseYou've already chosen the best response.1after you add 8.7 to both sides: x + 8.7 = 3y  8.7 + 8.7 = 3y, are you with me so far?
