n+2 3/5= 4
okay, so you have to get the variable alone and the numbers w/o a variable... so you subtract 2 and 3/5 from the other side (4)
n+2 3/5 - 2 3/5= 4-2 3/5
n= 1 2/5
(n equals one and two-fifths)

Just subtract 2 3/5 from both sides:
n = 4 - 2 3/5
n = 1 2/5

If you need help with subtracting fractions, convert them to improper fractions:
4 = 20/5
2 3/5 = 13/5

20/5 - 13/5 = 7/5
7/5 = 1 2/5

So the answer is n = 1 2/5

n+2 3/5 = 4

First, subtract 2 3/5 from 4 on both sides, cancelling out the 2 3/5 on the left.

4 - 2 3/5 = 1 2/5
To make it easier change both to fifths so it is
20/5 -13/5 = 7/5 = 1 2/5

And so, n = 1 2/5 or n = 7/5

5(2+n)=3(n+6) Firts you are able to desire to distribute so 5 situations 2 is 10 and 5 time n is 5n etc........and you get this 10+5n=3n+18 then you definitely subtract the ten from the 18 and get 8 and subtract the 3n from the 5n and get that.. 2n=8 then you definitely divide the two by using 8 and get that n=4 5(2+n)=3(n+6) 10+5n=3n+18 2n=8 n=4

N plus two and three fifths is equal to four
.. i hope i got that right.

N + 13/5 = 4 ... (converted to improper fraction
N = 4 - 13/5 ... (subtract 13/5 from both sides)
N = 20/5 - 13/5 ... (put them in the same terms)
N = 7/5 (do the subtraction)
n = 1 2/5 "N is equal to one and two fifths"

2 3/5 = 13/5

so,

n+ 13/5 = 4

n = 20/5 - 13/5

n = 7/5

which is the answer you are looking for. Good luck!

2 3/5
=(2*5+3)/5
=13/5

n+13/5=4
n+13/5=20/5
n=7/5
=1 2/5
