Morphology
The phrase 'simultaneous equations' is a straightforward adjective + noun composition: 'simultaneous' (occurring at the same time) modifies 'equations' (mathematical statements), so the meaning 'equations that hold/are solved at the same time' is directly derived from the parts. This compositional pattern is cross-linguistically common and follows regular English syntax, so a B1 learner who knows both constituents should be able to infer the MWE meaning.
Etymology
Simultaneous equations comes from the idea of several equations happening simultaneously, like rules that must all be true 'at the same time'. So, solving them means finding the numbers that make every equation true together.
