Ref Expression
Hypothesis deceq1i.1 A = B
Assertion deceq1i Could not format assertion : No typesetting found for |- ; A C = ; B C with typecode |-

Proof

Step Hyp Ref Expression
1 deceq1i.1 A = B
2 deceq1 Could not format ( A = B -> ; A C = ; B C ) : No typesetting found for |- ( A = B -> ; A C = ; B C ) with typecode |-
3 1 2 ax-mp Could not format ; A C = ; B C : No typesetting found for |- ; A C = ; B C with typecode |-
