What is the solution to the equation 3/5n-4/5=1/5n ?
explain !
a: n=-1
b: n=2
c: n= 5/3
d: n=5/2

The answer is 2.
Multiply to remove the fraction and set equal to zero and the solve. :)

The answer is B

Work:

3/5n-4/5=1/5n

-Combine like terms

3/5n-4/5=1/5n
-3/5n      -3/5n

-4/5=-2/5n

Divide by -2/5

-4/5=-2/5n
/ -2/5

(the 5 crosses out leaving -4/-2)

n=2 :)

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
