Answer 2

$⇒2(x - 3) + 3(y - 5) = 0 \\ ⇒2x - 6 + 3y - 15 = 0 \\ ⇒2x + 3y = 21.....(1) \\ \\ ⇒5(x - 1) + 4(y - 4) = 0 \\ ⇒5x - 5 + 4y - 16 = 0 \\ ⇒5x + 4y = 21......(2) \\ puting \: equation1 \: and \: 2 \\ ⇒10x + 15y = 105 \\ ⇒10x + 8y = 42 \\ ⇒7y = 63 \\ ⇒y = 9 \\ now \: puttin \: the \: value \: of \: y \: in \: (1) \\ ⇒2x + 3y = 21 \\ ⇒2x + 3 \times 9 = 21 \\ ⇒2x + 27 = 21 \\ ⇒2x = 21 - 27 \\ ⇒2x = - 6 \\ ⇒x = - 3$
