Answer:
[tex]s=4[/tex].
Step-by-step explanation:
We have been given an equation [tex]3r=10+5s[/tex]. We are asked to find the value of 's', when [tex]r=10[/tex].
To find value of 's', we will substitute [tex]r=10[/tex] in our given equation as shown below:
[tex]3(10)=10+5s[/tex]
[tex]30=10+5s[/tex]
Upon subtracting 10 from both sides of our given equation, we will get:
[tex]30-10=10-10+5s[/tex]
[tex]20=5s[/tex]
Now, we will divide both sides of our equation by 5.
[tex]\frac{20}{5}=\frac{5s}{5}[/tex]
[tex]4=s[/tex]
Therefore, the value of 's' is 4, when [tex]r=10[/tex].
