Keep in mind that you can gather only like terms. Two terms can be summed/subtracted if they involve the same powers of the same variables.

So, going point by point:

  1. We can subtract the terms, because they both involve the variable b, and we have 3b-7b = (3-7)b = -4b
  2. We can sum the terms, because they all involve the variable a, and we have a+a-5a = (1+1-5)a = -3a
  3. We can't sum this terms: 3 is a pure number, while 3r involves the variable r.
  4. We can only sum the two terms: we have 7t-8t-8 = (7-8)t-8 = -t-8
  5. We can't sum this terms: -20 is a pure number, while -15p involves the variable p.
  6. We can sum the terms, because they all involve the variable g, and we have -g-g-g = (-1-1-1)g = -3g

If you look at the position they all go up one and the value of terms all go up by 3 so 4+1=5 so 5 goes where no is and and 11+3=14
