Question

How do you solve 21s=3 ?

Answer 1

we can solve the question by this method-
21s=3
=s=3/21
=s=1/7

Answer 2

To solve the equation, you must isolate s, which means to get it alone on one side. Since you are multiplying s by 21, you must divide by 21 to get s alone. However, whatever you do to one side of the equation you must do to the other, so if you divide both sides by 21 and simplify it will give you s.


`21s=3 \\ \\ s= (3)/(21) \\ \\ s= (1)/(7)`
