If it is in equilibirum then the tension pulling to one side should equate the tension pulling to the other side so that there is a net zero force and hence in equilibrium.

Ah of course. I seem to have neglected the meaning of the 'equilibrium' part. It makes perfect sense now. Thanks!

@TeeEm

\text{Horizontal equilibrium} \Rightarrow \sum F_{i} = 0

, so the tensions are of the same magnitude as each other
