Hey!
------------------------------------------------
Let's solve for each option!
------------------------------------------------
Let's use -1:
2/3(6h - 9) = 6
2/3(6(-1) - 9) = 6
2/3(-6 - 9) = 6
2/3(-15) = 6
-10 ≠ 6
-1 is INCORRECT.
------------------------------------------------
Let's use 1:
2/3(6h - 9) = 6
2/3(6(1) - 9) = 6
2/3(6 - 9) = 6
2/3(-3) = 6
-2 ≠ 6
1 is INCORRECT.
------------------------------------------------
Let's use 3:
2/3(6h - 9) = 6
2/3(6(3) - 9) = 6
2/3(18 - 9) = 6
2/3(9) = 6
6 = 6
3 is CORRECT.
------------------------------------------------
Let's use 5:
2/3(6h - 9) = 6
2/3(6(5) - 9) = 6
2/3(30 - 9) = 6
2/3(21) = 6
14 ≠ 6
5 is INCORRECT.
------------------------------------------------
Answer:
C) 3
