Question

Find the value of 7w+7 given that 3w-8=7. Simplify your answer as much as possible.

Answer 1

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

Answer 2

Answer:

42

Step-by-step explanation:

3w-8=7

   +8  +8

$\frac{3w}{3}$=$\frac{15}{3}$

w=5

7w+7

7(5)+7

35+7

42
