Solution:
Find 1/3 of 63.
63 / 3 = 21
21 students gave a speech today.
63 - 21 = 42
Find 2/3 of 42.
42 / 3 = 14
14 x 2 = 28
28 of the remaining students gave their speeches.

If you need an explanation on how then let me know :)
Substitute value of y from equation 1st into 2nd,
5x + 2y = 7
5x + 2(x - 7) = 7
5x + 2x - 14 = 7
7x = 7 + 14
x = 21 / 7
x = 3
Now, y = 3 - 7 = -4
In short, Your Answer would be Option B) (3, -4)
Hope this helps!
Answer:
5-³=1/5³=1/125
-5-³=-1/125
(-5-³)-¹=-5-³*-¹=-5³=-1/125
(-5-³)^0=-5-³*0=-5^0=-1
