Answer:
As

Therefore, option C is true.
Step-by-step explanation:
Given the expression

as

so the expression becomes




Hence,

Therefore, option C is true.
A+s=70, s+l=80, l+a=80
from the first s=70-a which makes the second:
70-a+l=80
-a+l=10
a=l-10 which makes the third:
l+l-10=80
2l-10=80
2l=90
l=45
So Liam weighs 45 kg.
