Best ResponseYou've already chosen the best response.0it says y = 3x + 3 and y = x  1, so if y is equal to both of those things can you set those things equal to each other?

Best ResponseYou've already chosen the best response.0ok so you have y = 3x + 3 and y = x  1 so what is 3x + 3 equal to 3x + 3 = ?

Best ResponseYou've already chosen the best response.0do you see how i substituted the value of y from one equation into y in the other, that is substitution

Best ResponseYou've already chosen the best response.1this is what I normally use y = y regardless of how it is expressed example 10 = 6 + 4 and 10 = 8 + 2 10 = 10 so 6 + 4 = 10 + 2
