Question

Simplify the expression 3n - 2(n+5).

a) -5n - 10
b) -5n + 10
c) n - 10
d) n + 10

Answer 1

To simplify the expression 3n - 2(n+5), distribute the -2 to the terms inside the parentheses, combine like terms, and the simplified expression is n - 10.

Step-by-step explanation:

To simplify the expression 3n - 2(n+5), we can start by distributing the -2 to the terms inside the parentheses:

• -2 * n = -2n
• -2 * 5 = -10

So the expression becomes 3n - 2n - 10. Combining like terms, we have n - 10 as the simplified expression.

Therefore, the correct answer is c) n - 10.
