Distributive Property
Subtraction Property of Equality
Combine Like Terms
Multiplication Property of Equality
Division Property of Equality
Given
Addition Property of Equality

Answer 1

Explanation:

• 7x + 3x - 18 = 6(x + 3) === Given
• 10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 3
• 10x - 18 = 6x + 18 === Distributive Property === 6(x + 3)
• 10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides
• 4x - 18 = 18 === Combine Like Terms === 10x - 6x
• 4x = 18 + 18 === Addition Property of Equality === +18 both sides
• 4x = 36 === Combine Like terms === 18 + 18
• x = 36 / 4 === Division Property of Equality === /4 both sides
• x = 9 === combine like terms??

That doesn't use the multiplication property but that's all of the rest of them.
