Answer:
2n = 12
Step-by-step explanation:
4n-2n+4 = -1+17
add -1 and 17
4n-2n + 4 = 16
combine like terns
2n+ 4 = 16
subtract 4 from each side
2n+4-4 = 16-4
2n - 12
Answer:
(A) [tex]2n=12[/tex]
Step-by-step explanation:
The given equation is:
[tex]4n-2n+4=-1+17[/tex]
Solving the above equation, we get
Step 1. [tex]4n-2n+4=-1+17[/tex]
solving the RHS of the above equation, we get
Step 2. [tex]4n-2n+4=16[/tex]
Solving the LHs of the above equation, we get
Step 3. [tex]2n+4=16[/tex]
Step 4. [tex]2n=12[/tex]
⇒[tex]n=6[/tex]
Therefore, the value of n is [tex]6[/tex] and teh next step is [tex]2n=12[/tex].
Hence, option (A) is correct.
