How do you solve #19=a+5#?
a = 14
The way you solve this is by subtracting 5 form both sides. You must SUBTRACT because you have to take the opposite of the function that which is occurring in the equation. Once you do that you will receive your answer.
You need to get the like terms on one side (integers on one side, variables on the other).
When you do something to one side, you have to do it to the other. So, subtract 5 from both sides so that you will have only a on one and only an integer (the answer) on the other.
