EDIT: Solved! Thanks for the help.
I've been at this forever, so I finally gave up and I'm going to try here....
J+2T=9
J+4L=9
.5J+3T+2L=15
I need to find one J, one T, and one L. I've only been taught elimination and substitution (and graphing) so our teacher gave us this problem to try out. Problem is its a lot more difficult then the ones we go over in class.
I know the answers are (from asking a fellow classmate)
t=3.5
j=2
L=1.75
But I have no idea HOW to get those answer, and I need to show my work! Does anyone know how you would use elimination and substitution (and graphing) to get the answer??
TL;DR
J+2T=9
J+4L=9
.5J+3T+2L=15
Using elimination/substitution/graphing how would I get the answer?

Solve T in terms of J, then solve L in terms of J, then substitute into the 3rd eqution to get J by itself and solve for J, then plug it back into the others.
