Explanation:

First, you distribute 2 among 2x and -4. This leaves you with 4x - 8 = 11 because when you distribute, you multiply both numbers inside the parenthesis by the number outside of it. Then, you need to eradicate the 8 on the left of the equal sign, so you add 8 to -8 to make it 0, and add 8 to 11 to make it 19. This leaves you with 4x = 19. Finally, you must divide 4x and 19 by 4, leaving you with x = 4.75 or 4¾.

1. (2x - 4)(2) = 11

2. 4x - 8 = 11

3. 4x - 8 + 8 = 11 + 8

4. 4x = 19

5. 4x/4 = 19/4

6. x = 4.75 or 4¾

Answer:

x = 19/4

Explanation:

(2x - 4)(2) = 11

We can rewrite the equation in a more simple form.

2(2x - 4) = 11

Apply distributive property.

4x - 8 = 11

Get 4x alone. To get 4x alone, add 8 to both sides.

4x - 8 + 8 = 11 + 8

4x = 19

Get x alone. To get x alone, divide both sides by 4.

4/4x = 19/4

x = 19/4

I hope this helps! Let me know if I got anything wrong or if you need any more help.
