Question

Solve for n

2n − 3/5=5

Enter your answer in the box.
n =

Answer 1

n=14
2·14=28
28-3=25
25÷5=5

Answer 2

`n=(28)/(10)=2.8`

Explanation:

We have the expression
`2n-(3)/(5)=5` we have to find the value of n, then the first step is add
`(3)/(5)` in both sides of the equation:

`2n-(3)/(5)=5\\\\2n-(3)/(5)+(3)/(5)=5+(3)/(5)\\\\2n=5+(3)/(5)\\\\2n=(5.5+3)/(5) \\\\2n=(28)/(5)`

Now we have to divide both sides of the equation in 2:

`2n=(28)/(5)\\\\(2n)/(2)=((28)/(5))/(2)\\\\n=(28)/(2.5)\\\\n=(28)/(10)=2.8`

Then n=2.8
