Best ResponseYou've already chosen the best response.0I said to distribute, not add them together... \(4(x7)+3(x+9)=4x+28+3(x+9)\) I distributed the 4, now do something similar with \(3(x+9)\) and show me what you got.

Best ResponseYou've already chosen the best response.0ok, so we have \(4(x7)+3(x+9)=4x+28+3(x+9)=\\ 4x+28+3x+27\)

Best ResponseYou've already chosen the best response.0if you have 3 of something and you add 4 more, then you have 7 of that something the something here is x, so 3x+4x=7x make sense?

Best ResponseYou've already chosen the best response.0ok so \(4x+3x + 28+27 = x+55\)
