Question

How do you evaluate `7.575+ 2.3n - 3.845- 0.2= 1.1+ 1.4n`?

Answer 1

`n=-2.7`

Explanation:

`7.575+2.3n−3.845−0.2=1.1+1.4n`

`2.3n+3.53=1.1+1.4n` simplify the left hand side

`2.3n=1.4n-2.43` subtract 3.53 from both sides

`0.9n=-2.43` subtract `1.4n` from both sides

`n=-2.7` divide both sides by 0.9
