Thread: 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.

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

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

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

Try to finish.

-2.8p +5.7 You're truly a genius, thanks.
