x + 2y = t + p
2p = x + y
(t - y) + y = p + y
Having trouble with this equation, I need to get it in terms of: t + x + p
and lowest possible values.
I thought with n variables, you needed n equations. This has 4 variables, but only 3 equations.
I gather the idea is to eliminate one variable and get three equations with three variables. I could probably solve it from there, but I keep going in circles trying trying to create new equations.
thanks
Thanks for the replies.
The original problem contains symbols, which I have turned into equations. I'm pretty sure they're accurate.
The question offers sever solutions to the question of what is equal to t + x + p.
The answers are:
2t + y
3x
2p + t
2y + x
3t
p + t + y
Ok, maybe this makes a big difference. I just assumed it could be done without the answers without looking at them properly.
You state that each of these is equal to p + t + x:
2t + y
3x
2p + t
2y + x
3t
p + t + y
...and the values of the 4 variables are:
x = 5
y = 1
t = 4
p = 3
This means p + t + x = 3 + 4 + 5 = 12; BUT only 3t = 12
And if p + t + x = p + t + y
then x = y
But x = 5 and y = 1
Told you before: your problem is BADLY stated;
suggest you ask someone to help you decipher
those mysterious "symbols" you refer to
Well, I don't think it's that badly stated. By design, the problem is supposed to be somewhat confusing. I'll try to be clearer next time.
It also possible it cannot be solved by equation, I don't know.
They are simply symbols, there is nothing to decipher.suggest you ask someone to help you decipher
those mysterious "symbols" you refer to
The equations are constructed from the symbols.
