Answer:
166 marbles
Stepbystep explanation:
O  44 = L
O  48 = J
O  6 = L + J
I want to isolate O here
O = 44 + L
Plug it in
44 + L  6 = L + J
38 + L = L + J
38 = J
Now we know that Jack has 38.
O  48 = J
O  48 = 38
O = 86
Now we know Oscar has 86.
O  44 = L
86  44 = L
42 = L
Lily has 42.
38 + 86 + 42 = .....166
They have 166 coins altogether  Also Happy New Year!!! :D

Answer:
b; 166 coins
Stepbystep explanation:
let o = oscar
let l = lily
let j = jack
o = l + 44
o = j + 48
o = l + j + 6
you can combine the first 2 equations together using substitution
l + 44 = j + 48
then reorder the 3rd to have l in front
l = o + j + 6 >
l = o  j  6
o  j  6 + 44 = j + 48
then simplify the equation down
o = 2j + 10
then use the 2nd equation as substitution for o
j + 48 = 2j + 10
simplify
j = 38
finally you find o and l
38 + 48 = o > o = 86
86 = l + 44 > l = 42
last but not least you add them together
38 + 86 + 42 = 166
b is the correct answer
