What does the equation 15 g equals 23 2g?

The equation ( 15 , \text{g} = 23 , 2g ) seems to involve a misunderstanding in notation or units. If it is intended to represent a balance or equivalence, it may require clarification on what "2g" signifies. If "2g" refers to grams, then the equation could imply a relation between two quantities, but as written, it is not mathematically valid. More context is needed to provide a precise interpretation.
