the right answer is actually 30,60,90, I got the answer right on the test
Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6
3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
I hope this helps! Let me know if you need me to explain why I did some things :)

Answer:
None on the above.
Step-by-step explanation:
Here’s what I got:
1/5^-1.
3+(-4)=-1
5^-4/5^3 = 1/5^-1
A, B, and C. all of them are reasonable choices and wouldn’t give any conclusion, because not everyone has the flu
