<h3>What is equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

given:

7x + 3x - 18 = 6(x+3)

7x + 3x - 18 = 6x+18 [Distributive Property]

10x-18= 6x+18 [Addition Property of Equality]

10x-6x= 18+18 [Combine Like Terms ]

4x=36 [Subtraction Property of Equality]

4*x=36 [Multiplication Property of Equality]

x=36/4 [Division Property of Equality]

x=9
