Simplify the following expression: (x − 8y) − (2x − 4y). if the final answer is written in the form ax by, what is the value of b? (no options) 2. simplify (4x − 6) − (3x 6). x − 12 −x − 12 x 12 −x 12

If you would like to simplify the expression (x - 8y) - (2x - 4y), you can do this using the following steps:

(x - 8y) - (2x - 4y) = x - 8y - 2x + 4y = -x - 4y

ax + by = -x - 4y
a = -1
b = -4

The value of b would be -4.

 
If you would like to simplify the expression (4x - 6) - (3x + 6), you can do this using the following steps:

(4x - 6) - (3x + 6) = 4x - 6 - 3x - 6 = x - 12

The correct result would be x - 12.
