try this it will definately help you, in understanding the linear in - equation.. Solve the given: i. 7 - 2x > - 11 ; ii. -5x + 4 ≤ 2x - 10 ; iii. -3 ≤ 2x + 1 < 7 ; Solutions i. 7 - 2x > -11 -(2x) > -18 (by using subtraction rule) -(2x)/-2 < -18/-2 (by using division rule) X < 9 ii. -(5x) + 4 < 2x -10 -(7x) + 4 < -10      (by using subtraction rule) -(7x) < -14            (by using subtraction rule) X > 2                     (by using division rule) iii. -3 < 2x + 1 < 7 -4 < 2x < 6             (by using subtraction rule) -2x < x < 3             (by using division rule) Posted by Aliena | Posted Date: 2/12/2013 2:52:20 AM
