- Lecture 1: Solving Formula For A Variable: 1
In this video I will list, explain, and show an example on solving linear equations: 1) move all terms with L to the left side. Move all other terms to the right side OR flip the equation around: 2) factor out an L (if more than on term contains the L); 3) divide both sides by the factor of L. I will find L=? for P=2W+2L. This is the is the equation of the length of the perimeter equals 2 times the width plus 2 times the length.
