Answer 2

$Given \: pair \:of \: linear \: equations :$

$4x - 5y + 16 = 0 \: ---(1)$

$and \: 2x + y - 6 = 0 \: ---(2)$

/* Multiplying equation (2) by 5 and add with equation (1) , we get */

$10x+5y-30 + 4x - 5y + 16 = 0$

$\implies 14x - 14 = 0$

$\implies 14x = 14$

$\implies x = \frac{14}{14}$

$\implies x = 1$

/* Substitute x = 1 in equation (1) , we get */

$4\times 1 - 5y + 16 = 0$

$\implies 4 - 5y + 16 = 0$

$\implies -5y + 20 = 0$

$\implies -5y = -20$

$\implies y = \frac{-20}{-5}$

$\implies y = 4$

Therefore.,

$\green { x = 1 \: and \: y = 4 }$
