Answer:

x = 8

Step-by-step explanation:

Let's call the unknown number x

Then, four times a number can be written as 4x and two times that same number and 16 can be written as 2x+16

So, the expression that describes the complete sentence is:

4x = 2x + 16

Now, we can solve for x. So, subtracting 2x from both sides:

4x - 2x = 2x + 16 - 2x

2x = 16

Dividing by 2, we get:

2x/2 = 16/2

x = 8

Therefore, the unknown number is x = 8
