Find the value of 7w+7 given that 3w-8=7.
Simplify your answer as much as possible.
2 answers:
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:
42
Step-by-step explanation:
3w-8=7
+8 +8
=
w=5
7w+7
7(5)+7
35+7
42
