Step-by-step explanation:
Ответ:
? = 0
2 ÷ 3 = 0.67
2/3 = 0.67
a + 8/3 - 2/3 = ?
? = 0
8 ÷ 3 = 2.67
8/3 = 2.67
a + 8/3 - 2/÷ = ?
? = 0
a(3) / 3
3(a) + 8 / 3
3(a) + 6 / 3
We get "6" we added 3a + 3 & that gives you 6
3(a) + 6
a + 2 = 0
-2. -2
0a. -2
a - 2 = 0
0 - (-2) = -2
Therefore your answer would have to be: "a =-2" (option 2)
