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

Answer:

$s=4$.

Step-by-step 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.

$\frac{20}{5}=\frac{5s}{5}$

$4=s$

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