please help me with question no.3​

Answer 1

Answer:

=8x+5y=9----------equation 1st

=3x+2y=4------------equation 2nd

now,

from equation 1st

8x=9-5y

x=9-5y÷8

now put the value of x in equation. 2nd

=3(9-5y÷8)+2y=4

=27-15y÷8+2y=4

=27-15y+16y÷8=4

=27+y=32

=y=32-27

=y=5

now put the value of y in equation 1st

=x=9-5×5÷8

=x=-16÷8

=x= -2

hence,x= -2 and y= 5
