Once again, I'll try to illustrate each for you. Hopefully these will start to make sense after doing a few.
1. 2(x+7) + 10
2. 2(x-7) + 10
4. 2x + (7+10)
Another key word I look for is "Sum". So when they say "Two times the sum of...", in your mind you should think:
2( ___ + ___ )
Same thing with difference. "Two times the difference of..."
2( ___ - ___ )
