1. The first problem is to solve the equation $$7r + 2 \times 7r + 3 = -(7)(-2r)$$ for $r$.
2. First, simplify the left side by distributing and combining like terms.
3. The left side is $$7r + 2 \times 7r + 3 = 7r + 14r + 3 = 21r + 3$$.
4. The right side is $$-(7)(-2r) = 14r$$.
5. So the equation becomes $$21r + 3 = 14r$$.
6. Subtract $14r$ from both sides:
$$21r + 3 - 14r = 14r - 14r$$
$$\cancel{21r} + 3 - \cancel{14r} = 0$$
$$7r + 3 = 0$$.
7. Subtract 3 from both sides:
$$7r + 3 - 3 = 0 - 3$$
$$7r = -3$$.
8. Divide both sides by 7:
$$\frac{7r}{\cancel{7}} = \frac{-3}{7}$$
$$r = -\frac{3}{7}$$.
Final answer: The value of $r$ is $-\frac{3}{7}$.
