​

Answer 1

Answer:

Hope that this answer is helpful to you

Answer 2

Step-by-step explanation:

9x+4y=5.............(I)

4x-5y=9.............(II)

Doing equation (I) × 4 and equation (II) × 9

36x+16y = 20

36x-45y = 81

Subtracting both the equations,

y = -1

Now,

4x-5y=9

4x=9-5

x=4/4

x=1

Therefore, x = 1 and y = -1
