Answer 2

Answer:

Hii,

Step-by-step explanation:

$\huge\underline{\underline{\boxed{\boxed{\mathcal\pink{Answer:-}}}}}$

$\sf\bold{underline{Given:-}}$

::::---- 3x + 2y = 15 ( Eq. 1 )

::::---- 2x + 3y = 20 ( Eq. 2 )

$\huge\bf\bold{\underline{Adding \: equation \: (1) \: and \: (2), \: we \: get,}}$

$\:${ 3x + 2y = 15 }

$\:${ 2x + 3y = 10 }

$\:$+_______________

$\:${ 5x + 5y = 25 }

5x + 5y = 25

::::::) 5( x + y ) = 25

::::::) x + y = 25/5

::::::) x + y = 5

Therefore, the value of ( x + y ) is equal to 5.
