Theorem imasival 12949

Description: Value of an image structure. The is a lemma for the theorems imasbas 12950, imasplusg 12951, and imasmulr 12952 and should not be needed once they are proved. (Contributed by Mario Carneiro, 23-Feb-2015.) (Revised by Jim Kingdon, 11-Mar-2025.) (New usage is discouraged.)

Distinct variable groups:   F, p, q   R, p, q   V, p, q   ph, p, q

Allowed substitution hints:   B( q, p)   .+ ( q, p)   .+b ( q, p)   .xb ( q, p)   .x. ( q, p)   .X. ( q, p)   U( q, p)   Z( q, p)

Proof of Theorem imasival

Dummy variables f r v are mutually distinct and distinct from all other variables.
