find x

[Crimsonthread]

Right, Greek! According to the rules of the game, though, you should wait until the original poster confirms your answer before posting another question. Just for future reference.

x=7

(x^2) / 4=(x^3)-15x

[Crimsonthread]

X^3+7=50x

I'm sorry I mucked up Mistery

Yes Crimson it was 6.

No problem It's just important that we follow the rules from the first post, so that we don't get a mess here

It's Crimson's turn

Yes Crimson it was 6.

[Crimsonthread]

It's the same as "x squared." Or x times x. Or, if there's a different number after the ^(like x^y) then x multiplied by x y times.

....wait, did I confuse you more? How bout an example, just in case...

If x=2, then x^2 would be 4. x^3 would be 8, and so on.

[SimplyCrazy]

What does the ^ mean? I've ever used that in maths before!

[Crimsonthread]

Absolutely correct, Lovelylilyfairy!

And would your x be 6?

[Mistery]

Lovelylilyfairy, please wait for a confirmation before you post the new one

[Lovelylilyfairy]

x=-1/3

x^2 + 5x = 11x

[Crimsonthread]

Was this one too hard? Should I post another?

[Crimsonthread]

Ah, yes, they both work!

Mkay, here's a harder one for you!

(x-9)/(x-2)=(x+3)/(x+1)

[Mistery]

Lol, that's correct, although I've thought of 7

Your turn

[Crimsonthread]

NO! NOT AT ALL! I meant -5. (I think....)

(And I teach math... I shouldn't have missed that! O'course, we don't learn negatives in 5th grade.... so I have an excuse. )

[Mistery]

Are you sure
