Mastering this technique allows us to solve many more real life problems. For example, like the problem below, we are trying to find the speed in a distance equation. We are given the speed and distance, but we are trying to find the time. Since we know that Distance = Speed * Time, we are able to easily position the data given into the formula equation.
Given that the distance = 93, speed = (2x-10), and time = 1.5, find the speed the car was driving at.
We have to solve for .
We can distribute this equation.
Further simplify by adding 60 to both sides.
