3(9x)/4x = 5x+4.5 |
|
I figured I would make a math game for us. The rules are: |
|
3(9x)/4x = 5x+4.5 |
|
TLS, I think you might be mistaken... 3*9 ≠ 18, and x=0 in 3(9x)/4x = 5x+4.5 is undefined. I got |

^arnt you suppose to have two equations for that? unless you meant to say x>y by one or two or something |

I know how systems of equations work, Ive done em toooo much, lol. but I forgot you said we could do graphical problems too. |

Let me rephrase: there is only one set of integers (x,y) such that sqrt(17+sqrt(264)) = sqrt(x) + sqrt(y). If x or y is any other value, there is a y or x that satisfies the equation, but one of them will not be an integer. |

Algebra, eh? Ok: |

gah, its only annoying me because I forgot what really changes things if they are integers. Ive been all the way through calc 4 with relative ease but I forgot basic stuff like this lol. closest Ive come is x =19, y = 2? |

the difference between sqrt(x) and sqrt(y) is approx. 5,766 |
|
Oops, I edited my post. |
|
y = 5.766(5.766 - 2*sqrt(x)) + x |
|
That is about right, but I've checked it only mentally. Err... Where's your equation? O.o |

I derived the formula from a circle |
|
He's right, you only took the positive square roots. |
|
Ah, I see. I zoomed out and it's... still not a circle. That's an ellipse. |

Hang on a min, I think I made some mistake... |

All these questions so far have been disgusting. |

I've got myself a new one. This one should be correct. |

1 + 6 = 7, by the way. |
