Solve -12x > 30, when
(i) x is a natural number. (ii) x is an integer.
-12x > 30
(∵ -12 < 0)
∴ (i) When , there is no solution
∴ The solution set is .
(ii) When
The solution set is
3(x – 1) ≤ 2 (x – 3)
Hence,
24x < 100
∴ (i) When
∴ Solution set is
(ii) When
The solution set is
Solve 3x + 8 > 2, when
(i) x is an integer. (ii) x is a real number.
3x + 8 > 2
3x > 2 - 8 3x > - 6 x > -2
∴ (i) When
x = -1, 0, -1, 2, 3, ........
The solution set is
(ii) When
The solution set is
