Chelsea shows her work in finding the solution to 40x– 5 = 2+ 3(x– 3). After
checking her answer in the original equation, she found that it did not work. Where did she make a mistake?
a. step 1: she distributed incorrectly
b. step 2: She subtracted 3x incorrectly
c. Step 3: she’s simplified incorrectly
d. step four: she subtracted 5 instead of adding 5

Need on this geometry question. explain how you did it.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
