B + F = 2.25
B + S = 1.4
F + S = 2.45
Add Eq 1 and Eq 2
2B + F + S = 2.25 + 1.4
2B + 2.45 = 3.65
2B = 1.2
B = 0.6
Go back and solve for the rest

b + f = 2.25
b + s = 1.4
f + s = 2.45
b + f = 2.25
–b – s = –1.4
add
f – s = 0.85
f + s = 2.45
add
2f = 3.3
f = 1.65 ⬅
s = 2.45 – f = 0.80 ⬅
b = 2.25 – f = 0.60 ⬅
check
b + f = 2.25
1.45 + 0.60 = 2.25 ok
b + s = 1.4
0.60 + 0.8 = 1.4 ok
f + s = 2.45
1.65 + 0.8 = 2.45 ok
