>>> 4x – 2(x + 4)
First: distribute the 2 with both terms in the parenthesis >
4x – 2(x) - 2(4)
4x – 2x - 8
Sec: combine "like" terms >
2x - 8

Simplifying
4x + -2(x + 4)
Reorder the terms:
4x + -2(4 + x)
4x + (4 * -2 + x * -2)
4x + (-8 + -2x)
Reorder the terms:
-8 + 4x + -2x
Combine like terms: 4x + -2x = 2x
-8 + 2x

4x – 2(x + 4) =
4x - 2x -8 =
2x -8
2x = 8
x = 8:2
x = 4
Solution: {x E R | x = 4}
Answer is in alternative a.

4x-2(x+4)
first use the distributive property. you get:
4x-2x-8
then add like terms(4x and -2x). you get:
2x-8, so your answer would be a.
hope that helps!
