Question

shane_b · Answer

T=2J
M=3J
T+M+J=210

It's a system of equations...can you solve that?

shane_b · Answer

It's not even really a system...just plug in for T and M in the last equation and solve for J.

shane_b · Answer

Once you have J, you can easily figure out T and M given the first 2 equations.

shane_b · Answer

Do you need help going from there?

**
Ted=2x
Julie=x
Mike=3x

* Ted+Mike+Julie=210

Substitute the values given above to *equation,
combine like terms and solve for x. Then substitute again to ** to find each weight.
