1. **State the problem:** Solve the linear equation $$-4(-6u+6) - 5u = 7(u-1) - 2$$ for the variable $u$.
2. **Apply the distributive property:** Multiply inside the parentheses.
$$-4(-6u+6) = -4 \times -6u + (-4) \times 6 = 24u - 24$$
$$7(u-1) = 7u - 7$$
So the equation becomes:
$$24u - 24 - 5u = 7u - 7 - 2$$
3. **Combine like terms on each side:**
Left side: $$24u - 5u = 19u$$
Right side: $$-7 - 2 = -9$$
So the equation is:
$$19u - 24 = 7u - 9$$
4. **Isolate variable terms on one side and constants on the other:**
Subtract $7u$ from both sides:
$$19u - \cancel{7u} - 24 = \cancel{7u} - 9 - 7u$$
which simplifies to:
$$12u - 24 = -9$$
Add 24 to both sides:
$$12u - 24 + 24 = -9 + 24$$
which simplifies to:
$$12u = 15$$
5. **Solve for $u$ by dividing both sides by 12:**
$$u = \frac{15}{12}$$
Simplify the fraction by dividing numerator and denominator by 3:
$$u = \frac{\cancel{15}^5}{\cancel{12}^4}$$
6. **Final answer:**
$$u = \frac{5}{4}$$
