To solve this, follow these steps:
5x + 27 = 9 (x+3) - 4x
Distribute the 9 within the parenthesis:
5x + 27 = 9x + 27 - 4x
Then combine like terms:
5x + 27 = 5x + 27
These two then cancel each other out completely.
This is an identity because an identity in math is when both equations equal each other, which is shown above.
Hope this helps!
Check the picture below.
doesn't that make it just a 20 x 14? well, surely you know what that area is.
There are 21 people on each team. First you can divide 252 and 12. You get 21. To check you can then multiply 12 and 21 and get 252
