Answer:

X = 9

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.

Hey there!

The answer is
9

We will start by forming an equation to solve this.

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

So:


2x+7=25

Now we solve this equation:


2x+7=25


2x=18


x=9

Have a super awesome day!
