Answer 1

$\huge\mathfrak{Heya}$

$\mathsf{Given \ equation \ :-}$

$\mathsf{x + y = 6}$

$\mathsf{and}$

$\mathsf{x - y = 3}$

$\mathsf{Adding \ both \ these \ equations.}$

$\mathsf{We \ get}$

$\mathsf{2x = 9}$

$\mathsf{x = 9/2}$

$\mathsf{Put \ this \ value \ in \ 1st \ equation.}$

$\mathsf{We \ get}$

$\mathsf{y = 6 - 9/2}$

$\mathsf{y = 3/2}$

$\huge\mathbb{Hope \ this \ helps.}$

Answer 2

x+y=6

x-y=3 adding the both equation

_____

2x=9

. '. x= 9/2

Substituting the value of x in equation (1)

x+y= 6

9/2+y=6

. '. y= 6-9/2

. '. y=( 12-9)/2

. '. y= 3/2
