Question

Drag a statement or reason to each box to complete this proof. If −2(x+1)=8, then x=−5. Statement Reason 1. −2(x+1)=8 Given 2. −2(x+1)−2=8−2 3. Simplifying 4. x+1−1=−4−1 5. Simplifying

Answer 1

Answer:

1) Given −2(x+1)=8

2) Division Property of Equality (dividing both sides of the equation by -2)

3) $\frac{-2(x+1)}{-2}=\frac{8}{-2}$

4) Simplifying

5) x+1=-4

6) Substraction Property of Equality (substracting 1 on both sides of the equation)

7) x+1−1=−4−1

8) Simplifying

9) x=-5
