Answer:
the first expression
Step-by-step explanation:
There are no variables, and you've included the answer already, so I'm not sure what you're asking for..
Assuming that you are trying to find the values of a and s;
(2a+5s=41)3 -----> 6a+15s=123
-(3a+6s=54)2 -----> 6a+12s=108
6a+15s=123
-6a+12s=108
___________
0 + 3s=15
s=15/3
s=5
2a+5(5)=41
2a=41-25
2a=16
a=16/2
a=8
Hope I helped :)
