General Formulas and Concepts:
Pre-Algebra
Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Step-by-step explanation:
Step 1: Define
Identify
[tex]\displaystyle x - 2y = 1[/tex]
Step 2: Solve for y
- [Subtraction Property of Equality] Subtract x on both sides: [tex]\displaystyle -2y = 1 - x[/tex]
- [Division Property of Equality] Divide -2 on both sides: [tex]\displaystyle y = \frac{1 - x}{-2}[/tex]
- Rewrite: [tex]\displaystyle y = \frac{x - 1}{2}[/tex]
