Question

mathdummy has a quick question what are the common factors that need to be canceled?

7/5 (5x+30/7) -6

Answer 1

I know that the answer is x+6 .... but how/why

Answer 2

\[\frac{ 7 }{ 5 } * (\frac{ 5x+30 }{ 7 }) - 6= 0\]

Answer 3

Like that right?

Answer 4

yes, sorta, this is part of a function , and I don't understand the cancel common factor part...

Answer 5

May I see the whole function?

Answer 6

sure... \[f(x)= \frac{ 7 }{ 5 } x -6 and g(x) = \frac{ 5x+30 }{ 7 }\]

Answer 7

inserting g(x) in function of f(x)

Answer 8

Hmm, okay then.

Answer 9

sorry, forgot to put what we are going for in the long run...

Answer 10

Ah, I got it..

Answer 11

becomes:
x
