Question

Evaluate. Let n = 2. Enter the answer in lowest terms. 

Answer 1

First you do the top
8n+3n-7=8*2+3*2-7=16+6-7= 22-7=15
Then you found out the bottom
6*2n-3(n-1)=6*2*2-3(2-1)=6*2*2-3*1=6*4-3*1=24-3*1=24-3=21
15/21 is your answer.
Hope this helps! :)

Answer 2

Numerator:
8n+3n-7
= 11n-7

Plug n=2 in 11n-7, we have:
11*2-7= 15

Denominator:
6*2n-3(n-1)
= 12n-3n+3 (distributive property)
= 9n+3

Plug n=2 into 9n+3, we have:
9*2+3= 21

15/21
= (15/3) / (21/3)
= 5/7

The final answer is 5/7~
