Solving the System of Equations - Intro to Physics

[farragoprismproductions]

Didn't know it was appropriate to substitute forces like that! Although, you need to know when the right time to do so is. In this case, I can see why. You could also do process of elimination as well with Ft and -Ft; just see what you can cancel on both side when adding this systems of equations together on both of their sides. Anyways, thanks so much.
