Question: 8. 13 = -2(3 - 4) + 3y
13 = -2 - -8y + 3y
- 11y
1. **State the problem:** Solve the equation $$8 \cdot 13 = -2(3 - 4) + 3y$$ for $$y$$.
2. **Rewrite the equation:** The original equation is $$8 \cdot 13 = -2(3 - 4) + 3y$$.
3. **Calculate the left side:** $$8 \cdot 13 = 104$$, so the equation becomes $$104 = -2(3 - 4) + 3y$$.
4. **Simplify inside the parentheses:** $$3 - 4 = -1$$, so $$104 = -2(-1) + 3y$$.
5. **Multiply:** $$-2 \times -1 = 2$$, so $$104 = 2 + 3y$$.
6. **Isolate the term with $$y$$:** Subtract 2 from both sides:
$$104 - 2 = 2 + 3y - 2$$
$$\cancel{104} - 2 = \cancel{2} + 3y$$
$$102 = 3y$$.
7. **Solve for $$y$$:** Divide both sides by 3:
$$\frac{102}{3} = \frac{3y}{3}$$
$$34 = y$$.
**Final answer:** $$y = 34$$.
