Foundations of Linear Equations in One Variable

Examples of linear equations:
- 3x + 7 = 22
- -2x = 14
- x/4 - 3 = 5
- 0.5x + 1.2 = 3.7

Non-linear equations you'll encounter later:
- x² + 3 = 12 (quadratic)
- 2/x = 8 (rational)
- √x = 4 (radical)

Addition ↔ Subtraction: If something's added to x, subtract it from both sides. If something's subtracted from x, add it to both sides.

Multiplication ↔ Division: If x is multiplied by a number, divide both sides by that number. If x is divided by a number, multiply both sides by that number.
