Answer : and When, Subtracting 3 from both the sides    Signs of 1 – 3x:

1 – 3x = 0 (Subtract 1 from both the sides and then divide both sides by -3)

1 – 3x > 0 (Subtract 1 from both the sides, then multiply by -1 on both sides and then divide both sides by 3)

1 – 3x < 0 (Subtract 1 from both the sides, then multiply by -1 on both sides and then divide both sides by 3)

Interval satisfying the required condition ≤ 0 , x > 0 or Or Now when, Subtracting 3 from both the sides    Dividing both sides by 3 Multiplying by -1 on both sides Signs of x - 1:

x – 1 = 0 x = 1 (Adding 1 to both the sides)

x – 1 > 0 x > 1 (Adding 1 to both the sides)

x – 1 < 0 x < 1 (Adding 1 to both the sides)

Interval satisfying the required condition: ≤ 0

x ≤ 1

Combining the intervals: such that x > 0
