Best ResponseYou've already chosen the best response.2(a+b+c)/(a'+b'+c')=11/13 13a+13b+13c=11a'+11b'+11c' (13a11a') + (13b11b') + (13c11c')=0 a (1311a'/a) +b (1311b'/b) +c(1311c'/c)=0 Now, a'/a =b'/b =c'/c = (1+a)/a So, (a+b+c) {1311(1+a)/a}

Best ResponseYou've already chosen the best response.2Similarly, a'(13a/a' 11) + b'(13b/b' 11) +c' (13c/c' 11)=0 (a'+b'+c') { 13a/(a+1) 11}=0

Best ResponseYou've already chosen the best response.2So, (a+b+c) {1311(1+a)/a}/(a'+b'+c') { 13a/(a+1) 11}=0 {13 11(1+a)/a}=0 13a1111a=0 2a=11 a=5.5
