Answer 2

${ \huge{\blue{qu}}}{ \huge{ \green{es}}}{ \huge{ \red{ti}}}{ \huge{ \pink{on}}}{ \huge{ \purple{ : - }}}$

${ \huge{ \pink{solve : }}}$

${ \huge{ \green{141x + 103y = 217 \: \: \: 103x + 141y = 27}}}$

$\huge{ \red{ an}}{ \huge{ \pink{sw}}}{ \huge{ \purple{er : - }}}$

${ \small{ \blue{141x + 103y = 217 - (a)}}}$

${ \small{ \blue{103x + 141y = 27 - (b)}}}$

${ \small{ \blue{adding \: \: a \: \: and \: \: b}}}$

${ \small{ \blue{244x + 244y = 244}}}$

$\small{ \blue{244(x + y) = 244}}$

$\small{ \green{(x + y) = 244 \: \244}}$

$\small{ \green{x + y = 5 - (c)}}$

$\small{ \green{subracting \: a \: and \: b}}$

$\small{ \green{38x - 38y = 190}}$

$\small{ \green{x - y = 190 \38}}$

$\small{ \red{x - y = 5 - (c)}}$

$\small{ \red{adding \: c \: and \: d}}$

$\small{ \red{x - y = 5}}$

$\small{ \red{x + y = 1}}$

$\small{ \red{ 2x = 6}}$

$\small{ \pink{x = 6 \2}}$

$\small{ \pink{x = 3}}$

$\small{ \pink{putting \: value \: of \: x \: in \: equation \: x - y = 5}}$

$\small{ \purple{3 - y = 5}}$

$\small{ \purple{y = - 2}}$
