**Hypothesis**
Ref	Expression
subi.0	⊢ [ ko'a / da ] broda

**Assertion**
Ref	Expression
subi	⊢ ge ganai da du ko'a gi broda gi su'o da zo'u ge da du ko'a gi broda

**Proof of Theorem subi**
Step	Hyp	Ref	Expression
1		subi.0	. 2 ⊢ [ ko'a / da ] broda
2		df-sub 449	. 2 ⊢ go [ ko'a / da ] broda gi ge ganai da du ko'a gi broda gi su'o da zo'u ge da du ko'a gi broda
3	1, 2	bi 101	1 ⊢ ge ganai da du ko'a gi broda gi su'o da zo'u ge da du ko'a gi broda
