Question

simplify:
see below>>>>>>>>>>>>>

Answer 1

\[\frac{ 5w }{ w-4 }=5+\frac{ 4w }{ w-4 }\]

Answer 2

What's the LCD?

Answer 3

w=-20+9w??

Answer 4

Multiply both sides of the equation by the LCD. The rational expressions will go away and you will have a simple linear equation to solve.

Answer 5

lcd is (w-4)

Answer 6

Right. Now multiply by that on both sides (don't forget to distribute to both terms on the RHS).

Answer 7

is the 5 seperate or together with the right fraction?

Answer 8

ok I got w=-20+9w

Answer 9

It is a separate term.

Answer 10

after you multiply by LCD, should have:

5w=5(w-4)+4w

Answer 11

I'm not sure how you got w=-20+9w..... that's not right.

Answer 12

w=5

Answer 13

Yup! :)

But make sure you figure out where your initial mistake was. :)

Answer 14

I think you subtracted the 4w from the LHS but did not take it off on the RHS. That's my guess.
