$\huge{\Answer}$

$\tt{x + y = 5 }$ ____×3
$\tt{2x - 3y = 4 }$

By adding , We get ,

$\tt{5x = 19 }$
$\tt{ x = 19 / 5 }$
$\tt{ y = 5 - 19/5}$
$\tt{ y = 6/5 }$

Step-by-step explanation:

x+y=5 ____×3

\tt{2x - 3y = 4 }2x−3y=4

By adding , We get ,

\tt{5x = 19 }5x=19

\tt{ x = 19 / 5 }x=19/5

\tt{ y = 5 - 19/5}y=5−19/5

\tt{ y = 6/5 }y=6/5
