Step-by-step explanation:

7x + 3x - 18 = 6(x + 3) === Given10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 310x - 18 = 6x + 18 ===  Distributive Property === 6(x + 3)10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides4x - 18 = 18 === Combine Like Terms === 10x - 6x4x = 18 + 18 === Addition Property of Equality === +18 both sides4x = 36 === Combine Like terms === 18 + 18x = 36 / 4 === Division Property of Equality === /4 both sidesx = 9 === combine like terms??

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

You can find it by multiplying the areas it show u
