Question

How do you solve `0.75s + 5= 0.50s + 9`?

Answer 1

`s=16`

Explanation:

First, take `0.75s` and `0.50s` as `75/100s` and `50/100s`.

Then it becomes

`(75/100s)+5=(50/100s)+9`

`(75s+500)/100=(50s+900)/100`

The `100` on both sides will get cancelled

`75s+500=50s+900`

`75s-50s=900-500`

`25s=400`

`s=400/25`

`s=16`
