# Solve the following inequation: |7x – 4| < 10 - Mathematics and Statistics

Sum

Solve the following inequation: |7x – 4| < 10

#### Solution

|7x – 4| < 10
– 10 < 7x – 4 < 10 .......[|x| < k is same as − k < x < k]
Adding 4 on both sides, we get
– 6 < 7x < 14
Dividing both sides by 7, we get
- 6/7 < "x" < 14/7
∴ - 6/7 < "x" < 2
∴ x takes all real values between -6/7 and 2.
∴ Solution set = (-6/7,2)
