Hello!

Answer:


\boxed{ \bf w~=~4}

________________________________________________

Step-by-step explanation:

7(w + 9) = 91

First, we must multiply everything in the brackets by 7.

= 7(w) + 7(9) = 91

= 7w + 63 = 91

Now, we must solve for w. To do this, we will need to isolate it by perfoming the opposite operation on 63. Since it is +63, we'll need to subtract it from both sides of the equation.

= 7w + 63 = 91

- 63 - 63

7w = 28

Since w is being multiplied, we'll have to perform the opposite operation (which is division).


(7w)/(7) = (28)/(7)

w = 4
