How do you know when to use the subtraction property of equality as a reason as opposed to subtraction of real numbers?  @dan815

dan815 · Answer

when you want to subtract same thing from both sides maybe? I dont understand the question

When you have an equation, and you subtract the same amount from both sides, then the reason is "Subtraction property of equality."
When you actually do a subtraction, the reason is "Subtraction of real numbers."
