Step 1
1) Given, x < 4
Solution is: ( , 4 )
2) Given, 8 x + 3 5
i.e., 8 x 5 3
i.e., x 8 / 8
i.e., x 1
Solution is: ( , 1 )
3) 4 m 5 m > 13
i.e., 4 m m > 13 + 5
i.e., 3 m > 18
i.e., m > 18 / 3
i.e., m > 6
Solution is: ( 6 , )
4) 12 x 2 > 10 x 14i.e., 12 x 10 x > 14 + 2
i.e., 2 x > 12i.e., x > 12 / 2
i.e., x > 6
Solution is: ( 6 , )
Step 2
5) 1 7 x < 36
i.e., 7 x < 36 1
i.e., x > 35 / ( 7 )
i.e., x > 5
Solution is: ( 5 , )
6) ( 1 / 2 ) x ( 3 / 4 ) ( 7 / 4 ) x 2
i.e., 2 x 3 7 x 8
i.e., 2 x 7 x 8 + 3
i.e., 5 x 5
i.e., x 1
Solution is: ( , 1 ]
7) 5 + 9 ( x 1 ) 3 2 ( x + 3 )
i.e., 5 + 9 x 9 3 2 x 6
i.e., 9 x 4 2 x 3
i.e., 9 x + 2 x 4 3
i.e., 11 x 1
i.e., x 1 / 11
Solution is: ( , 1 / 11 ]
