Question

(6-3x)>9 (6- 7/9x)=1 (2x-1)<6

Answer 1

(6-3x)>9

6 – 3x> 9

-3x > 9 – 6

-3x> 3   /: (-3)

x<  -1

 

 

(6- 7/9x)=1   

6 – 7/9x = 1

-7/9x = 1 – 6

-7/9 x = - 5    /* (-9/7)

x = -5 * (-9/7)

x = 45/7

x = 6  i 3/7

 

 

(2x-1)<6

2x – 1<6

2x < 6 + 1

2x < 7    /:2

x < 7/2

x < 3 ½
