Answer:

x > 11/-8

Explanation:

1/5(x + 2) -1/4(2-x)> 1/3(x + 4) -1/4(5-x)

=60×1/5(x +2)-60×1/4(2-x)>60×1/3 (x+4)-60×1/4(5-x)

=12(x +2)-15(2- x)> 20(x+4)-15(5-x)

=12x + 24 - 30 + 15x > 20x + 80 - 75 + 15x

=12x + 15x - 20x -15x > 80 -75 -24 +30

=27x -35x > 80 - 99 + 30

=-8x > 11

=-8x/-8 > 11/-8

=x > 11/-8.

Hence the truth set of the inequality is said that (x : x > 11/-8).
