Question

0.5s +1=7 + 4.5s
S =

Answer 1

`s = -(3)/(2)`

Explanation:

Solve for the value of
`s` :

`0.5s + 1 = 7 + 4.5s`

-Combine both
`0.5s` and
`4.5s` by subtracting
`0.5s` by
`4.5s` :

`0.5s + 1 - 4.5s = 7 + 4.5s - 4.5s`

`-4s + 1 = 7`

-Subtract
`1` to both sides:

`-4s + 1 - 1 = 7 - 1`

`-4s = 6`

-Divide both sides by
`-4` :

`(-4s)/(-4) = (6)/(-4)`

`s = -(3)/(2)`

So, the value of
`s` is
`-(3)/(2)`.
