Which expression has a simplified expression of 5 x - 12? 3(4 x - 4) - 7 x -3(4 x - 4) - 7 x 3(-4 x + 4) - 7 x -3(-4 x - 4) - 7 x

3(4 x - 4) - 7 = 5 x - 12

Step-by-step explanation:

Simplify the following:

3 (4 x - 4) - 7 x

3 (4 x - 4) = 12 x - 12:

12 x - 12 - 7 x

Grouping like terms, 12 x - 7 x - 12 = (12 x - 7 x) - 12:

(12 x - 7 x) - 12

12 x - 7 x = 5 x:

 5 x - 12
