Answer:
The unknown number is 110.
Step-by-step explanation:
Let the unknown number be n.
Then your number, doubled, is 200 + 20 (20 greater than 200), so the pertinent equation is 2n = 200 + 20, or 2n = 220.
Then n = 110.
Check: Is 2(110) = 200 + 20? Is 2(110) = 220? YES
Answer:
Let the number be x.
x doubled is 2x, and 2x is 20 greater than 200. So, we have this:
2x = 200 + 20
2x = 220
x = 110.
