Answer= n=5
Step-by-step explanation:
1.
Distribute- 3(n+2)-(n-1)=17
3n+6-(n-1)=17
Add the numbers- 3n+6-n+1=17
3n+7-n=17
Combine like terms- 3n+7-n=17
2n+7=17
2.
Subtract 7 from both sides- 2n+7=17
2n+7-7=17-7
3.
Simplify the expression- 2n+7-7=17-7
2n=10
4.
Divide both sides by the same factor- 2n=10
2n/2=10/2
5.
Cancel terms that are in both the numerator and denominator- 2n/2=10/2
n=10/2
Divide the numbers- n=10/2
n=5
