Question

Solve for n.
19n+20≥1

Answer 1

`19n + 20 \geqslant 1`

`19n + 20 - 20 \geqslant 1 - 20`

`19n \geqslant - 19`

`(19n)/(19) \geqslant ( - 19)/(19)`

`n = - 1`

Answer 2

`n\geq -1`

Explanation:

`19n+20\geq 1`

`(19n+20)+(-20)\geq 1+(-20)`

`19n\geq -19`

`(19n)/(19) \geq (-19)/(19)`

`n\geq -1`
