```							Dear StudentGiven, 3x – y = 3and9x – 3y = 9are the two equations.From 1st equation,we get,x = (3+y)/3Now, substitute the value of x in the given second equation to get,9(3+y)/3 – 3y = 9⇒9 +3y -3y = 9⇒ 9 = 9Therefore, y has infinite valuesand since,x = (3+y) /3,so x also has infinite values.Thanks
