Study Guide: Equal To
Definition
In mathematics, when two quantities or expressions have the same value, they are said to be "equal to" each other. The symbol "=" is used to express this relationship.
Example
Consider the following example:
If x = 5, it means that the value of x is equal to 5.
Properties of Equality
- Reflexive Property: For any real number a, a = a.
- Symmetric Property: If a = b, then b = a.
- Transitive Property: If a = b and b = c, then a = c.
Using the Equal Sign
When using the equal sign, it's important to remember that whatever is on the left side of the equal sign must be equal to whatever is on the right side.
Practice Questions
- Solve the equation: 3x - 4 = 14
- Determine the value of y in the equation: 2y + 7 = 15
