Answer:
10
Step-by-step explanation:
-3a=-24-6
-3a=-30/-3
a=10
Answer:
a = 10
Step-by-step explanation:
First, you want to add six to both sides, so there would be no more negative 6 on the right and 30 on the left.
Next, you want to divide three to both sides because there is still the 3a there and you want the a to be the only thing on the right. So 30 ÷ 3 = 10 and 3 ÷ 3 = 1, which can just be left as a.
Lastly, you want to flip your 10 = a, to a = 10. And there is your answer.
