Ooopss!! You are absolutely Adjuster, I completely missed that important clue to the answer. How silly of me.The value of R1 is not required explicitly because of the additional information given. The student is actually given the node voltage Va, and so can solve the problem.
Don't you think that the 5 volt potential and the 5.1 ohm resistor contribute to the votage at the junction the 10.3 and 5.1 ohm resistor?V=IR
V=ix*R3
V=4*10.3
V=41.2
