Launch Full VideoUnderstanding Algebra
Basic Principles
Algebra uses variables (usually x
or y
) to represent unknown numbers. The goal is to isolate variables to find their values.
- Use inverse operations to isolate variables
3x + 4 = 10
becomesx = 2
after steps- Check solutions by substituting back into original equation
Simplification Rules
Combine like terms and use distributive property to make expressions simpler.
Example:
3(x + 2) = 3x + 6
2x + 4x = 6x
