Question

Read the proof. Fill in the empty justifications.

Conjecture: If 3(x - 1) = -27, then x = -8.

3(x - 1) = -27 A. Given

3x - 3 = -27 B. _________________

3x = -24 C. _________________

x = -8 D. _________________

Answer 1

Take x=-8 in each equation. for example-> 3(x-1)=-27=>3(-8-1)=27H.P.

Answer 2

im still confused.

Answer 3

3x-3=-27
put -8 instead of x

3(-8)-3=-27
now solve it if u gt both sides equal then it's right otherwise it's wrong.
