Distributive property is an algebra property that we use all the time! When you see equations in the form of a(x+b), you can transform them into ax+ab by multiplying the terms inside a set of parentheses. In this section, we will make use of this property to help us solve linear equations.

Basic Concepts:Model and solve one-step linear equations: $ax = b$, $\frac{x}{a} = b$, Solving two-step linear equations using addition and subtraction: $ax + b = c$, Solving two-step linear equations using multiplication and division: $\frac{x}{a} + b = c$,

Basic Concepts:Solving linear equations using multiplication and division, Solving two-step linear equations: $ax + b = c$, ${x \over a} + b = c$, Solving linear equations using distributive property: $a(x + b) = c$, Solving linear equations with variables on both sides,

- Introductiona)
- What is Distributive Property?
- How to use distributive property to solve linear equations?

- 1.Solve the equation using model.a)$4\left( {x + 1} \right) = 12$b)$2\left( {x - 3} \right) = 8$
- 2.Solve.a)$3\left( {x - 9} \right) = 45$b)$7\left( {10 + x} \right) = 14$c)$- 15 = 3\left( {x - 6} \right)$d)$- 22 = 11\left( {x + 13} \right)$
- 3.John has a round table with a circumference of 314.16 cm, but it is too big for his new home. So, he cut off a 10 cm wide border around the edge.a)Write the equation that represents the situation.b)What is the circumference of the table now? Round your answer to two decimal places.
