Pre-algebra addition linear equations

As what you have learned so far with basic addition, pre-algebra addition is quite a different conversation. A pre-algebra equation may have the same element as addition, in which there are two addends and a sum. But the process of solving them are different although they both possess the same operation, one of the addends would be missing. To explain further, in a pre-algebra equation, whether it is subtraction or addition, there will be a missing number that is represented by a letter, most of the time by the letter x. The number that will be missing and replaced by “x” will be one of the addends and not the sum itself as that would be the same as good old addition and that’s not how pre-algebra works. So, if you encounter a linear equation with addition in pre-algebra, what you can do is the opposite of addition, which is subtraction. If you are wondering, how do you do subtraction with an equation that has addition as an operation, it is because the sum is already given, and one addend is missing. So, if you subtract the sum and the given addend of the equation, the missing addend will be the answer. Now, if you replace the difference to the missing addend, the equation will make sense.
