Question: User: 8.n-1.4=-6.3
6.3+1.4=7.7
12.n/7x=7.3
15.-2=6/70p
1. **State the problem:** Solve the equation $$8n - 1.4 = -6.3$$ for $$n$$.
2. **Add $$1.4$$ to both sides** to isolate the term with $$n$$:
$$8n - 1.4 + 1.4 = -6.3 + 1.4$$
which simplifies to
$$8n = -4.9$$
3. **Divide both sides by $$8$$** to solve for $$n$$:
$$n = \frac{-4.9}{8}$$
Show cancellation:
$$n = \frac{\cancel{4.9}}{\cancel{8}} \times \frac{-1}{1}$$
4. **Calculate the division:**
$$n = -0.6125$$
**Final answer:** $$n = -0.6125$$
