In this video, you'll learn how to solve systems of equations with three unknown variables. We walk you through two different methods: elimination and substitution.
In this video, we walk you through the step-by-step solution to a problem involving the deflation of an air mattress, as shown in the attached graph. We'll explore how to calculate the rate at which the air mattress is being deflated, determine the volume of air remaining after a specific time, and analyze whether the deflation rate changes over time.
