hi i'm new to maths so not sure exactly what section this should come under but i've been trying to figure it out for a while and still can't.
the question is: the point (k, 2k) lies on the line with equation 2x+3y-6=0. find the value of k.
the answer is in the back of the book but i really can't figure out how you would arrive at that answer with the information given.
any help would be much appreciated, thankyou
