Question

solve y 6.3=0.9y thats all the question i dont understand it so thats why im trying to get the answer to the problem

Answer 1

what it wants you to do is to put it into a form where on the one side of the equation there is y and nothing else. for this, we need to get rid of the 0.9.

how do we do that?

we divide both sides of the equation by 0.9:

6.3/0.9=y

that's ugly, right? but if both denominator and nominator are decimal fractions of the same sort; we can multiply both by 10 and get rid of the point:

63/09=y
and...

`(63)/(9) =7`


so basically 7=y, or y=7

and this is the solution!
