Question

How do you solve `15n+16+4n=130`?

Answer 1

`n=6`

Explanation:

first, combine like terms

`color(red)(15n)+16+color(red)(4n)=130`

`color(red)(19n)+16=130`

then, subtract 16 from each side

`19n+16color(red)(-16)=130color(red)(-16)`

`19n=114`

finally, divide both sides by 19

`(19n)/color(red)(19)=114/color(red)19`

`(cancel(19)n)/cancel(19)=114/19`

`n=114/19`

`n=6`

Answer 2

`n = 6`

Explanation:

`15n + 16 + 4n = 130`

Start by simplifying the equation

`19n + 16 = 130`

Subtract `16` from both sides

`19n + 16 - 16 = 130 - 16`

`19n = 114`

Divide both sides by `19`

`(19n)/19 = 114/19`

`n = 6" "` (Ans)
