Let the blank space be x. So we have the following


3+7+2=x+2

The main purpose is to find the value of x by applying mathematical operations on both sides of the equality sign.

First, we add the numbers on the left hand side. So we get


3+7+2=12=x+2

Now, we subtract 2 on both sides, so we get


x=12\text{ -2=10}

So, the value of x that makes the equation true is x=10. That is, option C
