Question

Which could be used to solve this equation? 3 and one-fifth + n = 9 Subtract 3 and one-fifth from both sides of the equation. 3 and one-fifth minus 3 and one-fifth + n = 9 + 3 and one-fifth Add 3 and one-fifth to both sides of the equation. 9 + 3 and one-fifth = 12 and one-fifth

Answer 1

ITS A

Explanation:

Answer 2

Subtract
`3(1)/(5)` from both sides.

Explanation:

We want to isolate the variable
`n`. To do this, we have to get rid of
`3(1)/(5)`, which we can do by subtracting itself, since it equals 0.

`3(1)/(5) + n =9`

`n = 5(4)/(5)`
