-3 ( 5x + 12) < 1.5x
=> - 15x - 36 < 1.5x
=> -13.5x < 36
=> x < - 360 / 135
=> x < -2.66
therefore, the correct option for the value not a solution to this is
A. -3

Ques. -3(5x+12) < (1.5)x
= -15x-36 < 1.5x
= -30x-72 < 3x
= -30x +30x -72 < 3x+30x
= -72 < 33x
= -72/33 < x or x > -72/33
= x > -2.18
Since x should always be greater than -2.18 so -3 can not be a solution for this inequality.
I hope it may help you. In second line I've multiplied 2 both side in order to make calculation part easy so don't be confused.
