Use the properties of operations to determine if each pair of expressions is equivalent.

1) 12(4 – 2x) ; 2 – 2x

2) 12(6x – 2) ; 3 – x

For each expression, use a property to write an equivalent expression. Tell which property you used.

3) CD =

4) x + 13 =

5) 4(2x – 3) =

6) 2 + (a + b) =

Combine like terms.

7) Y + 4 + 3( Y + 2 ) =

8) 2++43+4 2 =
