1 answer

To solve each of these inequalities, we need to isolate the variable "x" on one side of the inequality sign.

1. 5.14x + 2.25 > 15.1
Substracting 2.25 from both sides: 5.14x > 12.85
Dividing both sides by 5.14: x > 2.5

2. 1/x > 3.9
Multiplying both sides by x: 1 > 3.9x
Dividing both sides by 3.9: 1/3.9 > x
Rearranging: x < 1/3.9

3. x > 12.85

4. x > 6.71
