Theorem: LO.FirstOrder.Arith.Model.mod_mul_add' (Arithmetization/Basic/IOpen.lean)

State before:
M : Type u_1
inst✝⁶ : Zero M
inst✝⁵ : One M
inst✝⁴ : Add M
inst✝³ : Mul M
inst✝² : LT M
inst✝¹ : M ⊧ₘ* 𝐏𝐀⁻
inst✝ : M ⊧ₘ* 𝐈open
b a c : M
pos : 0 < b
⊢ (b * a + c) % b = c % b
Tactic:
simp [mul_comm b a, pos]
State after:
