1) -3x-3

2)4w+3x-7

combining like terms is just putting the numbers together, and matching the letters. Just watch your signs (-+)

1st question:

3x + 4 - 6x - 7

You would combine 3x and -6x,

4 and -7

3x + (-6x) = -3x

4 + (-7) = -3x

The simplified expression would be -3x - 3x.

2nd question:

2 + 4w + 3x - 9

You would combine 2 and -9, but NOT 4w and 3x because they don't have similar coefficients.  

2 + (-9) = -7

The simplified expression would be  4w + 3x -7

Hope this helped! Happy Thanksgiving!
