Its mathematical role is local: the equation assigns its value or job.
An author may choose this form to keep one x separate from other variables. No general convention makes it a particular number, operation, or object; read the formula's definitions.
Why encode bold script x separately?
Mathematical style can carry meaning, not just decoration.
By 1999, scientific publishers were already using styled alphabets in formulas. A proposal involving the STIX publishing project and MathML contributors sought separate plain-text characters so distinctions between math alphabets could survive on the web and in text search.
Fonts draw script letters differently; the encoded form tells you which mathematical style was chosen, not one master shape.
For equations that distinguish letter styles; in ordinary prose it reads as a specialist letter.
