Answer:

okokokokokokokokokokokokokokok

Answer 2

Answer:

8x+5y=9.....(1)

3x+2y=4.....(2)

from (1)

8x+5y=9

8x=9-5y

x=(9-5y)/8

putting value of x in (2)

3x+2y=4

3{(9-5y)/8}+2y=4

3(9-5y)+8(2y)=4×8

27-15y+116y=32

27+y=32

y=27-32

y=5

putting y=5 in(2)

3x+10=4

3x=4-10

3x-6

x=-6/3

x=-2

x=-2,y=5
