The expression "4n 12 3n - 3" seems to be missing some operators. Assuming you meant "4n + 12 + 3n - 3," you can combine like terms. This simplifies to (4n + 3n) + (12 - 3), resulting in 7n + 9. If the intended expression is different, please clarify.

What value of n makes this sentence true 3n and ndash 2 4(n plus 3)?

To solve the equation (3n - 2 = 4(n + 3)), start by distributing the 4 on the right side: (3n - 2 = 4n + 12). Rearranging gives (3n - 4n = 12 + 2), which simplifies to (-n = 14). Thus, (n = -14).

The expression (3n + 4n - 14) simplifies to (7n - 14) by combining the like terms (3n) and (4n). This represents a linear expression in terms of (n).
