What are Linear Inequations?
A linear inequation is an algebraic expression involving a linear polynomial and inequality symbols such as:
- Greater than (>)
- Less than (<)
- Greater than or equal to (≥)
- Less than or equal to (≤)
Unlike equations, inequations do not have a single solution. Instead, they represent a range of values that satisfy the given condition.
For example:
- 2x + 3 > 7
- 3x – 5 ≤ 10
The solutions to these inequations are usually represented on a number line or in interval notation.
