Question

What is the value of s in the equation 3r=10+5s when r=10

Answer 1

3*10 = 10+5*s
30 = 10+5s
20 = 5s
s = 4

Answer 2

`s=4`.

Explanation:

We have been given an equation
`3r=10+5s`. We are asked to find the value of 's', when
`r=10`.

To find value of 's', we will substitute
`r=10` in our given equation as shown below:

`3(10)=10+5s`

`30=10+5s`

Upon subtracting 10 from both sides of our given equation, we will get:

`30-10=10-10+5s`

`20=5s`

Now, we will divide both sides of our equation by 5.

`(20)/(5)=(5s)/(5)`

`4=s`

Therefore, the value of 's' is 4, when
`r=10`.
