Absolute Value Equation
1. Stating the problem: Solve the equation $$|X + 1| = 5$$.
2. Recall that absolute value equation $$|A| = B$$ (where $$B \geq 0$$) can be rewritten as two separate equations: $$A = B$$ or $$A = -B$$.
3. Applying this to $$|X + 1| = 5$$:
i) $$X + 1 = 5$$
ii) $$X + 1 = -5$$
4. Solve each equation separately:
For i) $$X + 1 = 5$$:
Subtract 1 from both sides:
$$X = 5 - 1$$
$$X = 4$$
For ii) $$X + 1 = -5$$:
Subtract 1 from both sides:
$$X = -5 - 1$$
$$X = -6$$
5. Final answer: $$X = 4$$ or $$X = -6$$.
