What is Algebra?

Algebra is a way of using letters and symbols to represent numbers and relationships. For example, if x + 3 = 7, then we can figure out that x = 4.

Examples

• x + 5 = 9 → x = 4
• 2y = 10 → y = 5
• z - 7 = 1 → z = 8

Steps to Solve an Equation

1. Look at the equation.
2. Do the opposite operation (e.g., subtract instead of add).
3. Keep the equation balanced on both sides.
4. Check your answer by plugging it back in.
