1. The variable resistor \( R \) in the circuit below (see Figure 1 ) is varied until \( V_{X}=6 \mathrm{~V} \). What is the numerical value of \( R ? \) Hint: You should be able to solve this problem by using individual KCL or KVL steps, with each step yielding an equation with only 1 unknown that can be solved for (i.e. there is \( N O \) need for solving a system of equations).
