Equivalent Circuits & Source Transformation Example Problem

This is similar to problem 2.36 in "Circuit Analysis and Design" by Ulaby, Maharbiz, and Furse. This is a free/open educational textbook on basic circuit design found here: https://cad.eecs.umich.edu/ We will use our knowledge of series and parallel resistors to simplify the circuit. Finally we will also use a source transformation to further simplify the problem. This procedure is known as making an equivalent circuit. This is a common type of introductory engineering electric circuits problem.
