Question 426892: Where on the graph of 2x-6y=7 is the x-coordinate twice the y-coordinate?
Answer by sudhanshu_kmr(1152) (Show Source): You can put this solution on YOUR website!
x-coordinate = 2 * y-coordinate
put x =2y on equation,
2*2y - 6y = 7
=> 4y - 6y = 7
=> -2y = 7
=> y = -7/2
then x = 2 * (-7/2) = -7
so, required value : ( -7, -7/2 )
