-2(x - 4) > 10
- 2x + 8 > 10
- 2x + 8 - 8 > 10 - 8
- 2x > 2
- 2x / - 2 < 2 / - 2

the answer is :
2(x-4) > 10.
-(x-4) > 10/2. ->divide both sides by 2.
-(x-4) > 5.
(x-4) < -5. -> move the negative over, change the sign.
x-4 < -5. -> remove the brackets.
x < -5 + 4. -> add 4 to both sides.
x < -1.

Yes. In answer to the implicit question:
-2(x-4) > 10.
-(x-4) > 10/2. ->divide both sides by 2.
-(x-4) > 5.
(x-4) < -5. -> move the negative over, change the sign.
x-4 < -5. -> remove the brackets.
x < -5 + 4. -> add 4 to both sides.
x < -1.

x > 1
-2(x-4) > 10
-2x + 8 >10
-2x > 10-8
-2x > 2
x > 2/2 (when you carry -2 over to the other side, the sign
minus changes to +, so therefore, you cant write 2/-2, you will get the wrong answer of -1, it's 2/2, which gives 1)
x > 1

-2(x-4)>10
(x-4)<-5 ... divide both sides by -2 AND change the sign to <
becomes ...
x-4 < -5
x < -1 ... add 4 to both sides
remember that x < -1 and -1 > x indicates the same thing
