Given the equation:
3n + 2(1 - 4n)
Determine the equivalent expression.
Solution:
In order to determine the equivalent expression, we simply need to distribute 2 to each value inside the parenthesis, and then we combine similar terms.
= 3n + 2(1 - 4n)
= 3n + 2 - 8n
= 5n + 2
If we are asked to find for n, we need to transpose 2 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
5n = -2
n = -2/5
Final answer:
Simplified answer = 5n + 2
n = -2/5
