Hey there!

The answer is [tex]9[/tex]

We will start by forming an equation to solve this.

So we are starting with a number, [tex]x[/tex], then doubling it and adding [tex]7[/tex], which gives us 25.

So:

[tex]2x+7=25[/tex]

Now we solve this equation:

[tex]2x+7=25[/tex]

[tex]2x=18[/tex]

[tex]x=9[/tex]

Have a super awesome day!

Answer:

X = 9

Step-by-step explanation:

If you take 9, then double it, you get 18. 9+9 = 18. Then, you would add 7. 18 plus 7 is 25.

Hence, the answer to this problem is 9.
