Combine the rational expressions and simplify: 3x/9y + 8/x

Question

anonymous · Answer

I wrote it right.

anonymous · Answer

Here we go.
First we need a common denominator.
3x^2/9xy + 72y/9xy
Now we can add the numerators
$$(3x ^{2}+72y)/9xy$$
Since all terms are divisible by 3 we can simplify.
$$(x ^{2}+24y)/3xy$$

(x^2 +24y) /3yx.... do i need to slove d whole thing?? its easy.. just take lcm n solve.. thts it..

anonymous · Answer

That's what I get too. But it always says the answers I get like that are wrong. i think it has to do with the fact that it says combine AND simplify... Anyone know?

anonymous · Answer

Simplify is reducing the terms in the expression, because they are all divisible by 3.

anonymous · Answer

I will put in x^2+24y/3xy and see...
