# Math Help - Simplify expression

1. ## Simplify expression

Okay, I've been working on this problem, just don't get it.
-3 . 9p + 5 . 9 - ( 7p + .2 ) + 5 . 9p The periods are decimals.

2. ## Re: Simplify expression

$-3.9p + 5.9 - (7p+0.2 ) + 5.9p$

$=-3.9p+5.9-7p-0.2+5.9p$

$=-3.9p-7p+5.9p+5.9-0.2$

Try to finish.
