Answer :
Final answer:
To solve the equation 315 = 115 + 10w, subtract 115 from both sides and then divide both sides by 10 to isolate the variable w. The solution is w = 20.
Explanation:
The equation is represented as 315 = 115 + 10w. To solve this equation, we need to isolate the variable w.
First, subtract 115 from both sides of the equation:
315 - 115 = 115 + 10w - 115
This simplifies to:
200 = 10w
Next, divide both sides of the equation by 10:
200/10 = 10w/10
This simplifies to:
20 = w
Therefore, the value of w is 20.
