So,we have to work with the equation 3w-8= 7

We move eight to the other side as a positive number

3w= 8+7

3w=15

Divide both sides by three to get the value of w

15/3 = 5

Therefore, w is equal to five


Now that we have the value of w, we substitute it into 7w+7

7(5)+7

35+7= 42

Therefore the value of 7w+7 is 42

The value of 7w + 7 is 42.

Given that,

  • The equation is 3w + 8 = 7.

Calculation:

3w - 8 = 7

3w = 7 + 8

3w = 15

w = 5

Now

= 7w + 7

= 7(5) + 7

= 35 + 7

= 42
