Solve –12x > 30, when x is an integer.
उत्तर
The given inequality is -12x > 30.
= `(-12x)/(-12)< 30/(-12)`
= x < - `5/2`
The integers smaller than (-5/2) are…, -5, -4, -3.
Thus, when x is an integer, the solutions of the given inequality are …, -5, -4, -3.
Therefore, in this case, the solution set is {…, -5, -4, -3}.
