Solve the equation 7(w + 13) = 35. I know that it is:
7w + 20 = 35
- 20 - 20
7w/7 = 15/7
But I just don't know what 15 divided by 7 is as a fraction. Some one please help this is due in a week!

7(w+13)=35  {Here, 7 is wholly multiplied to w and 13}

7w+91=35

7w=35-91= -56

w=

w= -8

Proof:

7(-8+13)= -56+91= 35

Therefore, w= -8
