A variable circle always touches the line y-x=0 and passes though the point (0,0), the common chords of above cirlce and `x^2+y^2+6x+8y-7=0` will pass through fixed point , whose coordinates are

A variable circle always touches the line y =x and passes through the point ( 0,0). The common chords of above circle and x^(2) +y^(2)+ 6x + 8 y -7 =0 will pass through a fixed point whose coordinates are :

A variable circle which always touches the line x+2y-3=0 at (1, 1) cuts the circle x^2+y^2+4x-2y+1=0 . then all common chords of cricles pass through a fixed point(P,Q). THEN P+Q=
