x can be any of the following numbersx=(1,2,3,4......) since this is not an equality demand but one side being smaller than the other. All numbers will work if not o or less.
Note: For those who write 3/7=x it would be fine if both sides were = but they aren't however I agree all decimals bigger than 3/7 would work or fractions but not 3/7.

I know that this is solved as if both sides are equal so i think that x = 3/7 is correct

7x - 4 < 14x - 7
7x - 14x - 4 < -7
-7x < -7 + 4
x > -3/(-7)
x > 3/7
7x - 14x - 4 < -7
-7x < -7 + 4
x > -3/(-7)
x > 3/7
