Two More Questions For The Night.

I've been working on homework just about all afternoon and all night, getting to the point where I need sleep but before that I have questions about two more.. Questions? xD

-(19 - 3s) - (8s + 1) = 35

This one is really getting to me.. Since both sides are in parenthesis but I can't really well subtract or add them together. >.<;

5(x + 3) - 3x = 2(x + 8)

= 5x + 15 - 3x = 2x + 16

In this problem I know I need to merge 5x and 3x together to get any further and that is where I have a dilemma. 2x or -8x or neither! ;-;
