Question

What is the first step in solving the equation `3.5n+ 6.4=42.5`?

Answer 1

`n=36.1/3.5`

Explanation:

Given -

`3.5n+6.4=42.5`

1st step - Add `-6.4` on both sides

`3.5n+6.4-6.4=42.5-6.4`

`3.5ncancel(+6.4)cancel(-6.4)=36.1`

`3.5n=36.1`

2nd step - Divide both sides by `3.5`

`(3.5n)/3.5=36.1/3.5`

`(cancel(3.5)n)/cancel3.5=36.1/3.5`

`n=36.1/3.5`
