Hi ,
πx + y = 9
22x/7 + y = 9
y = 9 - 22x/7
1 ) if x = 7 ,
y = 9 - 22 = - 13
( x , y ) = ( 7 , - 13 )
2 ) if x = 14,
y = 9 - 44 = - 35
( x , y ) = ( 14 , -35 )
3 ) if x = - 7
y = 9 + 22 = 31
( x , y ) = ( - 7 , 31 )
4 ) if x = - 14,
y = 9 + 44 = 53
( x , y ) = ( - 14 , 53 )
I hope this helps you.

try this
66/7 + y = 9
y = 9 - 66/7
y = ( 63 - 66)/7
y = -3/7
( x , y ) = ( 3 , -3/7 )
66+y=9multiply by7 we get 63.y=63-66=-3
wrong
66 + 7y = 9 × 7 is correct
is it clear
