<u><em>The </em></u><u><em>number of trains</em></u><u><em> that arrived Dubai metro station on time is; 272 trains. </em></u>
<u><em /></u>
- We are told that 320 trains arrived the Dubai metro station in a week.
- Now, we are told that 5% got there early and 15% got there late.
This means, the percentage that got there on time is;
100% - % of trains that got there late.
- Therefore, percentage of trains that got there on time is;
100% - 15% = 85%
- Since 85% of the trains got there on time, then number of trains that got there on time is;
85% × 320 = 272
- Therefore, we can conclude that 272 trains arrived on time.

14 = 9 - x
First, subtract 9 from both sides.
14 - 9 = (9 - 9) - x
5 = -x
Now divide both sides by -1.
5/-1 = -1/-1x
-5 = x
The answer is x = -5.
Add like terms
-4x+x=-3x
6-2=4
So the simplified term is 4-3x
