Question
Let x and y be integers. Find the value of if
My solution
Fact 1) The L.H.S. must be a multiple of 3
Fact 2) If 0<y\leq{3}, then the R.H.S. is positive, but the L.H.S. is -ive, hence y>3
Fact 3) If y>22, a similar situation occurs, so 3<y<22
Fact 4) y cannot be a multiple of 3, as the L.H.S. would not be multiple of 3
Fact 5) I have stopped determining constraints and begun to guess the answer
Upon guessing, y=7 and x=2
So the value of follows
I think,
if you had 30x^2 + 517 could you not take x^2 to the other side?
and if you did and then divided (y^2) + (3x^2)(y^2)/(x^2)
Would that not cancel out the x2?
Giving you y^2 + (3)(y^2) = 30 + 517
??
I am probably breaking all kinds of rules but it seems that you loose x in that case and then you would have
4y^2 = 537
y^2 = 537/4
y = square root of (537/4)
I know I am all kinds of wrong I was just curious... Its ok to make a bit of fun of me I dont mind :P
