Question

How do you simplify `3 (4 + 5s ) - 12 + ( - 3s )`?

Answer 1

`12s`

Explanation:

`3(4+5s)-12+(-3s)`

`=12+15s-12-3s`

`=(12-12)+(15s-3s)`

`=0+12s`

`=12s`

Answer 2

The answer is `12s`.

Explanation:

Firstly you have to open the bracket `3(4+5s)` it will be `12 +15s` and the second bracket `+ (-3s)` will be `-3s`. So your equation will be `12 +15s -12 - 3s` then collect like terms, it will be `12 -12 +15s -3s`, then it will be `12s`.
