# Simultaneous Equations Watch

1. Could some help me solve the following system please?

1. 2P
2. 3Q
3. 4(1-P-Q)

Thanks a lot.

Edit: Could I set them as 2P=3Q=4(1-P-Q) obtain 6P-3Q=4 and then set that against 4(1-P-Q) and solve as a system of two equations?
2. Those aren't equations

Those aren't equations
Thanks for your reply. I thought someone may say that. Normally the technique I'm using churns out answers like 2P+(1-P)and 3P. I set them equal and solve for P. This is what it's turned out this time. I suppose I'm asking how to solve three equations in two unknowns? Thanks again, could you offer any further insight?
4. Perhaps my ignorance shining through but what are you trying to find exactly? Values for P and Q which satisfy...?

-
If 2P = 3Q = 4(1-P-Q), you can surely find values which satisfy the equation like any other simultaneous equations.

For example:
2P = 4(1-P-Q)
2P = 3Q
5. Well, if 2P=3Q, then using 2 and 3 gives 4-6Q-4Q=3Q, so Q is 4/13. That's if you're trying to find P and Q so that 1,2 and 3 are equal.

4-6Q-4Q=3Q, so Q is 13/4.

7. Whoops, hopefully the OP got their answer though.
