Choose all of the equations that have NO SOLUTION. 5x - 2 = -5(x + 2)
O 5(2x + 1) +1=3(x + 2)
08 (3 - 2) = -(8x - 3)
1+ 4x + 2x = 4(x + 5) – (8 – 2x)

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.
