| Concept | Example |
|---|---|
| Variable | x, y, etc. |
| Expression | 3x + 4 |
| Equation | 2x + 5 = 11 |
| Solving | x = 3 |
To solve equations, perform the same operation on both sides to isolate the variable. For example:
2x + 5 = 11
Subtract 5 from both sides: 2x = 6
Divide both sides by 2: x = 3
Combine like terms (terms with the same variable part):
3x + 2y - x + 4 = (3x - x) + 2y + 4 = 2x + 2y + 4
Always plug your solution back into the original equation to verify:
If you get x = 3 for 2x + 5 = 11, check:
2(3) + 5 = 6 + 5 = 11 ✓
