Answer 2

Answer:

X = -2

Y= 5

Step-by-step explanation:

→ Solving the given equation By Elimination method :

8x+5y=9 __________ (1)

3x+2y=4 __________ (2)

→ Multiplying the equation (1) by 2 & equation (2) by 5.

We get,

16x+10y = 18

15x+10y= 20

→ Subtracting both the equations.

We get,

x = -2

→ Putting the value of x in equation (1).

8(-2) +5y = 9

-16+5y = 9

5y = 9+16

5y = 25

y = 25/5

y = 5
