Answer:
B) n=-2
Step-by-step explanation:
First, distribute.
7(1+4n)-5=-38+8n
7+28n-5=-38+8n
Combine like terms.
2+28n=-38+8n
To make solving the equation easier, subtract 8n first, so there isn't a negative variable.
2+28n=-38+8n
<u>-8n -8n</u>
2+20n=-38
Subtract 2 on both sides.
2+20n=-38
<u>-2 -2</u>
20n=-40
Divide by 20 on both sides.
20n=-40
<u>/20 /20</u>
n=-2
