Answer 1

a)3x+17<x=13
3x-x<=13-17
2x<=-4
x<=-4/2
x<=-2

b)6x-2>7x+8
6x-7x>8+2
-x>10
x<-10

c)x+4<12+9x
x-9x<12-4
-8x<8
x>-1

d)7+6x<2(5x-8)
7+6x<10x-16
7+16<10x-6x
23<4x

e)4x-11<x9+13
-11-13<9x-4x
-23<5x
x>-23/5

f)8x+3<9x-2
8x-9x<-2-3
-x<-5 /* -1
x>5

g)6-4x>7-6x
-4x+6x>7-6
2x>1
x>1/2

h)10x-9>-3(2-5x)
10x-9>-6+15x
10x-15x>-6+9
-5x>3
x<-3/5
