# Thread: Math Problem need EXPERT PO member Math CHAMPIONS

1. ## Math Problem need EXPERT PO member Math CHAMPIONS

having trouble with this:

y=3-3x
x-5y=-15

Tried Algebra Substitution n' Algebra Elimination

Damnit capt. I'm a Physicist not a [email protected]

2. x=0, y=3

3. Just for a more reasonable explanation, if you solve both in terms of y, you get:

y=3-3x
y=3+x

so 3-3x = 3+x, which balances to -3x = x (x can only be 0)

y = 3 - 3(0) = 3
y = 3 + (0) = 3

where you gettin y=3+x, second equation was x-5y=-15 which is y=(x+15)/5, which is y=x/5 + 3, just being nit picky, you get same answer.

Thanks for being nitpicky but yielding the same answer

6. very good riv.. now what is big stack against your 8-10 off?

7. HAHA... Madjek sounds like my HS Algebra II teacher. She would get so mad when I would look problems over and write the answers out without actually writing the process down on paper.

A3 vs. my KK is 98% to win

9. WHAT !! HUH ????? how many outs does that make ??

10. there are 48 unseen cards aside from the A3 and 2 kings.

On merge, there are 48 aces in the deck - so 47 left.
