Jawaban:
pertidaksamaan linear satu variabel
1 - (9 - x)/14 < 2 - (5 + x)/7 → Kedua ruas dikalikan sama dgn ( x 14 ).
1 . 14 - (9 - x)/14 . 14 < 2 . 14 - (5 + x)/7 . 14
14 - (9 - x) < 28 - 2(5 + x)
14 - 9 + x < 28 - 10 - 2x
5 + x < 18 - 2x
x + 2x < 18 - 5
3x < 13
x < 13/3 atau x < 4 ⅓
HP = {( x | x < 13/3 , x € R )}
