What is the value of n in the equation
1/2(n-1) - 3 = 3 - (2n + 3)?
1 answer:
Hey there! :)
1/2(n - 1) - 3 = 3 - (2n + 3)
Simplify.
1/2n - 1/2 - 3 = 3 - 2n - 3
Add like terms.
1/2n - 3 1/2 = -2n
Add 3 1/2 to both sides.
1/2n = -2n + 3 1/2
Then, add 2n to both sides.
1/2n + 2n = 3 1/2
Simplify!
2 1/2n = 3 1/2
Make everything into improper fractions!
5/2n = 7/2
Multiply everything by 2 to get rid of the denominators.
5/2n × 2 = 7/2 × 2
Simplify!
5n = 7
Divide both sides by 5.
n = 7/5
Hope this helped! :)

Answer:
I think that the answer is 2 power n , so A is the correct choice .
The anwer is 233,000 and that is the anwer so i need a thank you
Just divide by 4 on both sides to isolate n, that gets you 29.
