Variable line ax+by+c=0 passes a fixed point if a,b,and,c are three consecutive odd natural number the fixed point is

Dear student,
Let us assume any two equations following the given condition.
For instance,
x+3y+5=0 and 3x+5y+7=0
When we solve these two equations, we get the solution as (1,-2)
Therefore, the fixed point is (1,-2).
Regards.
