Hey there! :)
2(3/5n + 3) - (2/3n - 1)
Simplify.
(2 * 3/5n) + (2 * 3) - (2/3n -1)
Simplify.
6/5n + 6 - 2/3n + 1
Add like terms.
(6/5n - 2/3n) + (6 + 1)
Make the fractions have the same denominator by multiplying fraction 1 (6/5n) by 3/3 and fraction 2 (-2/3n) by 5/5.
6/5n * 3/3 = 18/15n
-2/3n * 5/5 = -10/15n
So, our new equation looks like this : (18/15n - 10/15n) + (6 + 1)
Simplify.
8/15n + 6 —> final answer.
Hope this helped! :)
