This is the Easter BunnyHe brings eggs to good boys and
girls.

This is the Distributive bunnyHe brings numbers to ( )
( x + 3 ) = 8 (2)(2)2

83-2
Created by Pat Prewitt, Central HS, Beaumont, TX
So now we have
(2) x + (2)3 = 8
2x + 6 = 8
And we loose the other ( )
Multiply out
Created by Pat Prewitt, Central HS, Beaumont, TX
Try another with distributive bunny
( 2x + 6 ) = 7 3 (3) (3)
Created by Pat Prewitt, Central HS, Beaumont, TX
And this gives us
3(2x) + 3(6) = 7
6x + 19 = 7
Remem
ber—loose the other ( )

Try these on your own
1. 3 ( x + 4 ) = 21
2. 2 ( x – 3 ) = 8
3. -2 ( c + 1 ) = -4
4. 2 ( 8 + t ) = 22 Created by Pat Prewitt, Central HS, Beaumont, TX
Answers 1. 3x +12 = 21 x = 3 2. 2x – 6 = 8 x = 7 3. -2c + -2 = -4 c = 1 4. 16 + 2t = 22 t = 3

( 3 + 5x ) + 5 = 18 5 (5) (5)
Remember: The bunny only give numbers to the ( )
Not in the ( ) no numbers for you.

•So now we have
(5)3 + (5)5x + 5 = 18
15 + 25x + 5 = 18
Created by Pat Prewitt, Central HS, Beaumont, TX
Try these on your own
1. 3 ( 2x – 1) + 6 = -15
2. 5 ( x – 12 ) + 10 = 100
3. 3x + 2 (5 – x ) = 12 Created by Pat Prewitt, Central HS, Beaumont, TX
Answers 1. 6x – 3 + 6 = -15 x = -3
2. 5x – 60 + 10 = 100 x = 30
3. 3x + 10 – 2x = 12 x = 2

So now we have

3 – 2x + -14 = 18

Created by Pat Prewitt, Central HS, Beaumont, TX
So now we have
2 (-) x + (-) 7 = 10 2 –x + -7 = 10 2 – 7 – x = 10- 5 – x = 10

Try these
1. 2 – 3 ( x + 4) = 17
2. 6 – 5 (m – 1 ) = 111
3. n – (3n + 4) = -6 Created by Pat Prewitt, Central HS, Beaumont, TX
Answers 1. 2 – 3 x – 12 = 17 x = -9
2. 6 – 5m + 5 = 111 m= -20
3. n –3n – 4) = -6 n = 1
