Answer:
x = 5
Step-by-step explanation:
This is a simple equation if you look at it right and don't get scared by the "x."
All we need to do is figure out what times 3 = 27. We can do this easily by diving 27 by 3.
27 ÷ 3 = 9
Since our "equation" is 3(x + 4) = 27 we know whatever is in the parenthesis () has to equal to 9. We already get 4 so:
5 + 4 = 9.
3 times 9 = 27.
5 is your answer.
<u>Hope this helps and have a nice day!</u>
