Find an equation for the line that passes through the points of intersection of the circles x^2+y^2=25, and x^2-3x+y^2+y=30 can you explain all the steps thanks

• x^2+y^2=25,
  and
  x^2-3x+y^2+y=30
  
  The points where 2 or more circles meet are the roots of the equations.
  hence solving these 2 eqns ( putting x^2+y^2=25 in other eqn), we get
  y= 3x+5 which is desired eqn of line.
