How did you get that the answer is x<3 if you don't know how to do it step by step? :P

What do you think you would do first?

anonymous · Answer

first multiply out the bracket on left side
2x+10>8x-8
then bring x's to left and constants to right
2x-8x>-8-10
-6x>-18
then divide accross by -6
x>3

2(x + 5) > 8x – 8
Solve the bracket first
2x+10 >8x-8
Subract 10 both sides
2x+10>8x-8
     -10      -10
---------------
2x  >8x-18

Shift 8x to the left
2x-8x>-18
-6x>-18
x>-18/-16
