Solving Inequalities

An inequality is a mathematical statement that compares two expressions using symbols such as <, >, ≤, or ≥.

The symbol '>' means 'greater than'. For example, a > 4 means 'a is greater than 4'.

The symbol '<' means 'less than'. For example, a < 6 means 'a is less than 6'.

The symbol '≥' means 'greater than or equal to'. For example, x ≥ 10000 means 'x is greater than or equal to 10000'.

The symbol '≤' means 'less than or equal to'. For example, k ≤ -11 means 'k is less than or equal to -11'.

Add 13 to both sides: y ≤ -2.

x must be less than 6.

The solution is all values of a that are greater than 6.

'At least' is represented by the symbol '≥'. For example, 'at least 10,000' is written as x ≥ 10000.

Subtract 3 from both sides: 2x < 8.
