Answer:


x=6

Explanation:

We can set up an equation with the information given:


6 ·
20+x ·
10+19 ·
1=199

We can simplify that to:


120+10x+19=199

Which is, simplified further:


139+10x=199

If we subtract 139 from both sides of the equation, we will get:


10x=60

Thus,
x=6.

Hope this helps :)
