What is answer for n 2(n-4)=-1

Answer 1

Greetings!

"What is answer for n:
`2(n-4)=-1`?"..

Solve using the properties of equality:
Distribute the Parenthesis.

`2*n-2*4=-1`
Simplify.

`2n-8=-1`
Add 8 to both sides.

`(2n-8)+8=(-1)+8`
Simplify.

`2n=7`
Divide both sides by 2.

`(2n)/2=(7)/2`
Simplify.

`n=7/2`
or

`n=3.5`

Hope this helps.
