Question

(x + 15) + 2(y + 6). Identify an equivalent expression.

Answer 1

First of all, we should try to distribute the 2 to the terms inside of the parenthesis.

\[(x + 15) + 2(y + 6) = (x + 15) + 2(y) + 2(6) = x + 15 + 2y + 12\]

Answer 2

Now combine all of the like terms ... what do you get afterwards?

Answer 4

combine the like terms in
\[x + 15 + 2y + 12 => x + (15 + 12) + 2y\]

Answer 5

Just evaluate 15 + 12

Answer 6

I think that it would be like:
\[\Huge \ x + 27 + 2y\]
