Best ResponseYou've already chosen the best response.1\(y = 2x + 19 \\ y = x + 7\) so go for \(y = y\) ie: \( \ \ 2x + 19 = x + 7\) and see where you get

Best ResponseYou've already chosen the best response.1\(\large −2x+19=x+7 \) \(\large −2x+19 (+ 2x)=x+7 (+ 2x)\) \(\large 19=3x+7\) \(\large 197=3x+77\) \(\large 12=3x\) \(\large 3x=12\) \(\large \frac{3x}{3}=\frac{12}{3}\) \(\large x = 4\) check: \(y = −2(4)+19 = 11\) and \(y =(4)+7\ = 11 \) \(\huge \checkmark \)
