1).5x-11,hp=
3).10-8x>2x+30,hp=

1. 5x-1<2x+5
=5x-2x<5+1
=3x<6
=x<6/3
=x<2
hp={x|x<2}

2. 2y-5>1
=2y>1+5
=2y>6
=y>6/2
=y>3
hp={x|x>3}

3. 10-8x>2x+30
=-8x-2x>30-10
=-10x>20
=x<20/-10
=x<-2
hp={x|x<-2}

maaf kalau salah ..

1. 5x-1 < 2x + 5
5x-2x = 6
3x = 6
X = 2
Hp {2}
2. 2y -1> 1
2y = 2
Y = 1
Hp {1}
