Question

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

Answer 1

= > 3r = 10 + 5s


Given that the value of r is 10.

Substitute the value of r in the equation.



= > 3( 10 ) = 10 + 5s

= > 30 = 10 + 5s

= > 20 = 5s

= > 5 × 4 = 5 × s

= > 4 = s




Hence, value of s is 4.

Answer 2

=> 3r = 10 + 5s
Put the given value in r
=> 3(10) = 10 + 5s
=> 30 = 10 + 5s
=> 30 - 10 = 5s
=> 20 = 5s
=> 20 / 5 = s
=> s = 4....... Here is the answer
