3-1/2n= 10?

Answer 1

3 - 1/2n = 10

2(3) - 2(1/2n) = 2(10)

6 - n = 20

6 - n - 6 = 20 - 6

- n = 14

- 1(- n) = - 1(14)

n = - 14

The answer is n = - 14

Answer 2

Hey, Layla

Why don't you look at your answer of n=-26. It is wrong and I will show you why:

3-1/2(-26)=10
3+13=10
16≠10

Therefore, n does equal -14 and I have proof to show you why:
3-1/2(-14)=10
3+7=10
10 does equal 10.

Next time, make sure you have the right answer before posting next time!

Answer 3

1/2n=n/2

3 - 1/2n=10
3- n/2=10
-n/2 =10-3
-n/2=7
-n=2x7
-n=14
n=-14

Answer 4

Multiply both sides by 2 to get rid of the fractions:
2(3-1/2n)=2(10)
6-n=20

Subtract 6 from both sides:
-n=14

Divide -1 from both sides:
n=-14

Check:
3-1/2(-14)=10
3+7=10
10=10

I hope this helps!

Answer 5

Is that 1/(2n) or (1/2)n?

Answer 6

I'm assuming you mean

3 - (1/2)n = 10

{It's difficult to tell without proper parethesis what you mean}

Moving the 3 over to the right hand side, we have

(-1/2)n = 7

Multiplying both sides by -2, we have

n = -14

Answer 7

n=-14
3 - (1/2 * -14) = 10
3 - (-7) =10
3 + 7 = 10

Answer 8

not sure if 1/2n mean (1/2)n or 1/(2n)
so heres the ans. for each case
--------------------------------
3-1/(2n)= 10
multiply both sides by 2n:

6n-1=20n
-1=14n
n= -1/14
------------------------------------
3-(1/2)n= 10
multiply both sides by 2:

6-n=20
-n=14
n= -14

Answer 9

3 - (-7) = 10
so, -7 = 1/2n
so, -14n = 1
therefore, -n = 1/14
therefore, n = -14

Answer 10

n equals to -14
