Question

9. Select all the equations that are equivalent to the equation. 3x - 4 = 5

A. 3x = 9
B. 3x - 4+4 = 5 + 4
C. x - 4 =2
D. x=9
E. -4 = 5 - 3x

Answer 1

A and B since adding 4 to each side makes it 3x=9 not being D since it asks “equivalent to the equation” and x would be 3 anyways. I don’t feel like explaining the rest but trust

Answer 2

Answer: It would be A, B, and lastly E.
