We expand the bracket using the distributive property to obtain,

Group similar terms to get,

Simplify to get,

We divide both sides of the inequality by -8 and reverse the sign to obtain,


QUESTION 3
Step 1.
Given:4(-6x – 3)+24x= -72x + 132
Step 2.
Distributive property:
-24x – 12 + 24x = -72x + 132
Step 3.
Combine like terms:
–12 = -72x + 132
Step 4.
Addition property of equality:
-144 = -72x
Step 5.
Division property of equality:
2=x
All the properties stated are correct.
