Answer 1

zad 2

a

-5x+4>-3x-10

-5x+3x>-4-10

-2x>-14 :(-2)

x>7

 

c

7x-21\-3<x |*(-3)

7x-21<-3x

7x+3x>21
10x>21 |\ 10

x>2,1

Answer 2

zad 1

2x/3 +x/6 -3x/2 = 0

4x/6 + x/6 - 9x/6 =0

-4x/6 = 0

x=0

zad2

a) -5x +4 > -3x -10

-2x > -14

x < 7

b) 5-3(x+6) > 2 + 5x

-3x -5x > 2+18-5

-8x > 15

x < -8/15

c) 7(x-3)/-3 < x

(7x -21)/-3 < x

7/-3x +7 -x < 0

4/-3x<-7

x > 21/4

d) 3x/5-x+4/10 > 0

-2x/5 > -4/10

x < 1
