Answer:
a linear equation
Step-by-step explanation:
6n+5=3n+20
<u>collect like terms</u><u>:</u>
6n-3n=20-5
3n=15
<em><u>divide both sides with the coefficient of n</u></em>
3n÷3=15÷3
n=5

Answer:
36
Step-by-step explanation:
2*n = what the expression says.

Step-by-step explanation:
Your question isn't well written but I saw an identical question:
A bookshelf is 42 inches long. Each book is 1 1/4 inches wide. How many books will fit on the shelf?
For us to solve this, we would divide the length of the bookshelf by the width of each book. This would be:
= 42 ÷ 1 1/4
= 42 ÷ 5/4
= 42 × 4/5
= 33 3/5
Therefore, the number of books that will fit on the shelf is 33.
