1. Jawaban apisindonesia
x + 8 < 5, x < 5-8, x<-3
3y - 4 > 11, 3y > 11+4, 3y>15, y> 15/3, y>5
3(x - 2) < x + 8, 3x-6 < x+8, 3x-x<8+6, 2x<14, x<14/2, x<7
1/2x + 4 > 2/3x + 3, dikali 6.
6 (1/2x + 4) > 6 (2/3x + 3)
3x + 24 > 4x +18, 3x-4x > 18-24, -x>-6, x>6
1/5(x + 6) < 1/3 (x - 2), dikali 15
15 [1/5(x + 6)]< 15 [1/3 (x - 2)]
3x + 90 < 5x -30, 3x-5x < -30-90, -2x < -120, x<60
