What is the best way to classify each equation? 22-3x+7x=4 (x+5),6 (2x-3=3 (3-5), 6x-14=2 (3x-7), 6x+3 (x-4) = 8 (x-3)

1. 22 - 3x + 7x = 4 (x + 5)

22 - 3x + 7x = 4x + 20

+3x + 3x + 3x

22 + 10x = 7x + 20

-7x - 7x

22 + 3x = 20

-22 - 22

3x = - 2

3 3

x = - 2/3

2. 6 (2x - 3) = 3 (3 - 5)

12x - 18 = 3 (-2)

12x - 18 = - 6

+18 + 18

12x = 12

12 12

x = 1

3. 6x - 14 = 2 (3x - 7)

6x - 14 = - 3x

6x - 14 = 2 (-7)

6x - 14 = - 14

+14 + 14

6x = 0

6 6

x = 0

4. 6x + 3 (x - 4) = 8 (x - 3)

6x + 3x - 12 = 8x - 24

9x - 12 = 8x - 24

-8x - 8x

x - 12 = - 24

+12 + 12

x = - 12
