Answer 2

★${\red{\underline{\bold{Given:-}}}}$

9x+4y=30................(i)

4y-x=10...................(ii)

★${\red{\underline{\bold{To\:find:-}}}}$

Value of X and Y.

★${\red{\underline{\bold{Step\:by\: step\: solution:-}}}}$

9x+4y=30................(i)

4y-x=10...................(ii)

•Take (i) no. equation→

9x+4y=30................(i)

•We can write the equation as

4y+9x=30................(i)

${\purple{\boxed{\bold{Apply\:the\: process\:of\: elimination}}}}$

4y+9x=30

4y - x =10

(-) (+) (-)

____________

10x = 20

→ x= 2

•Put the value of x=2 in the (ii)no. equation.

4y-x = 10

→ 4y-2 =10

→ 4y =10+2

→ 4y = 12

→ y = 3

★${\green{\huge{\bold{Answer:-}}}}$

$x = 2 \\ y = 3$
