Answer 1

Answer:

I hope its helpful for you

Step-by-step explanation:

$2x - 3y = 19.........(1)$

$3x - 2y = 21........(2)$

$solved \: by \: substitution \: method$

$x = 19 + 3y \div 2....(3)$

$put \: the \: value \: of \: x \: in \: eq \: (2)$

$3(19 + 3y \div 2)2y = 21$

$57 + 9y \div 2 - 2y = 21$

$57 + 9y - 4y = 42$

$57 + 5y = 42$

$5y = - 15$

$y = - 3$

$put \: the \: value \: of \: y \: in \: eq \: ......(1)$

$2x - 3 \times ( - 3) = 19$

$2x + 9 = 19$

$2x = 10$

$x = 5$
