Answer :

To solve the equation [tex]\( 5 + \square = 12 \)[/tex], let's determine the number that will make this statement true.

1. We start with the equation:
[tex]\[ 5 + \square = 12 \][/tex]

2. Our goal is to isolate the unknown number (represented by [tex]\(\square\)[/tex]). To do this, we need to move the 5 to the other side of the equation. We can do this by subtracting 5 from both sides of the equation:
[tex]\[ 5 + \square - 5 = 12 - 5 \][/tex]

3. Simplify both sides:
[tex]\[ \square = 12 - 5 \][/tex]

4. Perform the subtraction:
[tex]\[ \square = 7 \][/tex]

So, the number that, when added to 5, gives 12 is [tex]\( \boxed{7} \)[/tex].
Final answer:
7
5+7=12
