Answer:

let \\  - 4y + 11x - 67 = 0 \:  \:  \: be \:p \\ and \\ 2y + 5x + 19 = 0 \: be \: q \\ multiply \: 2 \: to \: q \: we \: get \\ 2q = 2(2y + 5x + 19)  \\  = 4y + 10x + 38 = 0 \\ add \: p \: and \: 2q \: we \: get :  \\ p + 2q  \\  =  (- 4y + 11x - 67) + (4y + 10x + 38) \\  = 21x  - 29 = 0 \\ x =  \frac{29}{21}
