Answer:
16
Explanation:
To solve this problem, we can use an equation. This allows for a simpler way of solving.
We can represent this problem as x4+15=79. We're representing the number we want to get as x, and since its multiplying it by 4, we just write it as x4. Also, dont forget to add the 15 to x4.
Finally, add the =79 to represent the answer to x4+15 to be 79.
Now, solve it.
Add subtract 15 on both sides to simplify.
4x+15=79
-15 -15
4x=64
Now, divide both sides by 4 to isolate x.
x=16
The answer is 16
Hope this helps!
