Answer:
Step-by-step explanation:
x + 2 + x + 4 = 34
2x + 6 = 34
2x = 28
x = 14
14 + 2 = 16
14 + 4 = 18
Answer:
B. 5
Step-by-step explanation:
To solve this equation, we need to subtract both, 9c - 3c:
Dividing by 6 at both sides of the equation
Then
Then the answer C = 8. (Option D)
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
