Penjelasan dengan langkah-langkah:

1.10x+11(<=)6x+43

10×-6x(<=)43-11

4x(<=)32

x(<=)8

x-8(<=)0

2.6y+7(>=)2y-9

6y-2y(>=)-9-7

4y(>=)-16

y(>=)-4

y+4(>=)0

3.5t-1<6-3(t-1)

5t-1<6t-6-3t+3

5t-6t+3t<-6+3+1

2t<-2

t<-1

t+1<0

4.4(2b-1)>5-2(b-8)

8b-4>5b-40-2b+16

8b-5b+2b>-40+4+16

5b>-20

b>-4

b+4>0

5.3x-2(5x+15)(<=)x+2

15x²+45x-10x-30(<=)x+2

15x²+45x-10x-x(<=)2+30

15x²+34x(<=)32

15x²+34x-32(<=)0
