Hello!!! Princess Sakura here ^^
Step-by-step explanation:
In all of these I just plugged in for x
Checking choice (1):
[tex]2x+1>15\\2(9)+1>15\\18+1 >15\\19>15[/tex]
This is true so it's not the right answer.

Checking choice (2):
[tex]2x+1>15\\2(7)+1>15\\14+1>15\\15>15[/tex]
This is false so this is the answer.
But we'll just check the others just in case.

Checking choice (3):
[tex]2x+1>15\\2(10)+1>15\\20+1>15\\21>15[/tex]
This is true so it can't be the answer.

Checking choice (4):
[tex]2x+1>15\\2(15)+1>15\\30+1>15\\31>15[/tex]
This is true so it can't be the answer.

Now we found out that the answer is Choice 2.
