Distributive Property
Multiplication or Division Property of Equality
Commutative Property
Given
Addition or Subtraction Property of Equality

Answer 1

4x − 1 = −2 (x + 1) ⇒ Given

4x−1=−2x−2⇒ Distributive property (since we've multiplied out -2(x+1))

6x−1=−2 ⇒ Addition or Subtraction Property of Equality (We've added 2x onto the 4x to get 6x)

6x=−1 ⇒ Commutative Property (We've moved -1 to the other side to get the sum -2+1 = -1)

x=−¹/₆ ⇒ Multiplication or Division Property of Equality (We divided both sides by 6)
