Solving P=P+Prt for r and t (literal equations)

In this video, we explore the magic of solving literal equations for a variable, specifically P=P+Prt for r and t. The key idea is to apply the opposite operations of the ones you see in the equation, and treat the letters as if they were numbers. We use the example of A = P + Prt and show how to isolate r and t. First, we isolate r by grouping the p and rt terms together and then dividing both sides by pt. This leaves us with A - P/pt = r. To solve for t, we group the P and r terms together and then divide both sides by Pr. This gives us A - P/Pr = t. It's all just multiplication, as we illustrate with simple numerical examples. Finally, we show that the equation is already solved for a, so nothing needs to be done. Remember, not everyone needs the same level of detail, but it's important to stress the basic operations and apply them to literal equations. 🤔💻🧐 Here are some common questions related to this topic 1.
