maths used to get to this point :-
(12L1+9L2)-(12L1+20L2)=3-8
-11L2=-5
L2=-5/11
L2=-0.4545
4L1+3L2=1
4L1+(3*-0.4545)=1
4L1-1.3635=1
4L1=1+1.3635
L1=2.3635/4
L1=0.590875
Hi All,
I too have this question and am a little confused. For the value of L2 I get -0.4545 but if I use this figure to get L1 I get 0.590875 which is nowhere near what you guys are saying.
If I use 0.4545 instead I get somehwere near the answers suggested on here.
Could someone please...
