Theorem 2 the elimination rule for multiplicationWhen a b c nachamnuan, actually, any backpack.(1) if ac = bc and c ≠ 0, then a = b.(2) if ab = ac and a ≠ 0, then b = c.
Theorem 2 rules to cut out for multiplication on a, b, c bordered any real number (1) if ac = bc and c ≠ 0, then a = B (2) If ab = ac and a ≠ 0 and b =. c
