"Algebra"
In this problem, we are trying to solve for x in the equation x+5=12x + 5 = 12x+5=12.
This means we want to find out what number x must be so that when we add 5 to it, the result is 12.
To do that, we need to get x all by itself on one side of the equation.
Since 5 is being added to x, we do the opposite operation, which is subtracting 5.
We subtract 5 from both sides of the equation because whatever we do to one side, we must also do to the other to keep it balanced.
After subtracting, the equation becomes x=7x = 7x=7.
This means x must be 7 to make the original equation true.
Finally, we can check our work by plugging 7 back into the original equation:
7+5=127 + 5 = 127+5=12, and since 12 equals 12, we know our answer is correct.
