Which step should be completed first to solve the equation ? a. add 14 to both sides. b. divide both sides by 3. c. divide both sides by −3. d. subtract 9 from both sides.
Given a peek at the equation, we would probably be able to make that recommendation in quite a short time. Without seeing the equation, there's no way.

i'm guessing it was a multiple first option was the correct answer
Given: ab ≅ cd and ad ≅ bc prove: abcd is a parallelogram. statements reasons 1. ab ≅ cd; ad ≅ bc 1. given 2. ac ≅ ac 2. reflexive property 3. △adc ≅ △cba 3. ? 4. ∠dac ≅ ∠bca; ∠acd ≅ ∠cab 4. cpctc 5. ∠dac and ∠bca are alt. int. ∠s; ∠acd and ∠cab are alt. int. ∠s 5. definition of alternate interior angles 6. ab ∥ cd; ad ∥ bc 6. converse of the alternate interior angles theorem 7. abcd is a parallelogram 7. definition of parallelogram what is the missing reason in step 3? triangle angle sum theorem sas congruency theorem sss congruency theorem cpctc
