Electric Circuit: Path of Least Resistance

[adz7861]

Homework Statement

The power dissipated by resistor X when the switch is closed

Relevant Equations

p=IV
p=I^2R
V=IR

I figured that when you close the switch the current from the upper cell will travel through the closed switch due to it being the path of least resistance, essentially the resistor between cells is unused (was my first thought). I'm not entirely sure how to progress with this question.

Despite the cell in series with it?
