Question

2x-3y=9;2x+y=13 in hindi ​

Answer 1

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

$2x - 3y = 9 \: ---(1)$

$and \:2x + y = 13 \: ---(2)$

/* Subtract equation (1) from equation (2) ,we get */

$\implies 4y = 4$

$\implies y = \frac{4}{4}$

$\implies y = 1$

/* Put y = 1 in equation (2), we get */

$2x + 1 = 13$

$\implies 2x = 13 - 1$

$\implies 2x = 12$

$\implies x = \frac{12}{2}$

$\implies x = 6$

Therefore.,

$\green { x = 6 , y = 1 }$

Answer 2

${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

${\red{\boxed{Given}}}$

$\sf\dashrightarrow \: pair \: of \: equations :$

$2x - 3y = 9 \: ---(1)$

$\:2x + y = 13 \: ---(2)$

$\sf\therefore subtract\:eq\:2 \:by\:eq1,$

$\implies 4y = 4$

$\implies y = \frac{4}{4}$

$\implies y = 1$

now,

$2x + 1 = 13$

$\implies 2x = 13 - 1$

$\implies 2x = 12$

$\implies x = \dfrac{12}{2}$

$\implies x = 6$

$x = 6 , y = 1$
