```Lesson 3
The Distributive Property
State whether the equation is true or not with the
given values.
1.
6x – 4y = 22 when x = 5 and y = 2
2.

3.
y = – 3x – 1 when x = – 2 and y = – 7
+ 5 = y when x = 6 and y = 11
Target:
Simplify expressions using the Distributive
Property and combining like terms.

Term: A number or the product of a number and a variable.

Constant: Term that has no variable.

Coefficient: The number multiplied by a variable in a term.

Distributive Property: A property that can be used to rewrite
an expression without parentheses.

Like Terms: Terms that have the same variable raised to the
same power.

Equivalent Expressions: Expressions that have the same
value.
For any numbers a, b and c:
a(b + c) = a ∙ b + a ∙ c
a(b – c) = a ∙ b – a ∙ c
Use the Distributive Property to simplify each expression.
2(x + 6)
2(x) + 2(6)
2x + 12

Simplify by combining like terms
– 5(2x – 1) + 3x – 2
– 10x + 5 + 3x – 2
– 7x + 3
Simplify each expression.
