y= 2

Step-by-step explanation:

I have attached a photo of solution with this....Hope you found your answer..

Answer 2

$2x + 3y = 4 - - - (1) \\ 3x - y = - 5 - - - (2)$

multiply eq (2) by 3

$9x - 3y = - 15$

by eliminating both the equations

we get,

$11x = - 11$

${\bold {\large {\boxed {\red {\mathcal {X=-1}}}}}}$

now for the value of y

put the value of x in equation (2)

$3 (-1)-y=-5$

${\bold {\large {\boxed {\red{\mathcal {Y=2}}}}}}$
