Question

Drag a statement or reason into the blank to complete this proof;

If −2(x+1)=8, then x=−5.

−2(x+1)/−2 = 8−2 _________
_________ Simplifying
x+1−1=−4−1 _________
_________ Simplifying

Options to fill in the blank:
Subtraction property of equality
Division property of equality
Distributive property of equality
x + 1 + -4
x = -5

Answer 1

\left[x \right] = \left[ 5\right][x]=[5]2(x+1)/−2 = 8−2 _________
_________ Simplifying

\left[x \right] = \left[ 2\right][x]=[2] = x + 1 + -4
x = -5
