An inequation is like an equation, but instead of an equals sign, it has a different symbol. The symbol tells us how the two sides of the inequation compare to each other.
Here are the symbols and what they mean:
< means "less than" means "greater than"
≤ means "less than or equal to" ≥ means "greater than or equal to" So, for example, the inequation 2x < 8 means "2 times x is less than 8". This tells us that x can be any number that makes the statement true. To solve for x, we can divide both sides of the inequation by 2:
2x < 8 x < 4
So x can be any number that is less than 4.
Another example is the inequation 3x + 5 ≥ 11. This means "3 times x plus 5 is greater than or equal to 11". To solve for x, we can start by subtracting 5 from both sides:
3x + 5 ≥ 11 3x ≥ 6
Then we can divide both sides by 3:
x ≥ 2
So x can be any number that is greater than or equal to 2.
I hope this helps you understand inequations!
