Question 1069784: Rewrite the rational expression as an equivalent rational expression with the given denominator.
5a+6/7a-49=?/7b(a-7)
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! you are starting with:
(5a + 6) / (7a - 49).
and you wind up with:
x / (7b(a - 7)
only thing i can think of is this.
start with (5a + 6) / (7a - 49).
multiply by b/b to get:
b * (5a + 6) / (b * (7a - 49)
factor out a 7 in the denominator to get:
b * (5a + 6) / (b * 7 * (a - 7).
this can also be shown as:
b * (5a + 6) / (7b * (a - 7))
basically, what you are doing is multiplying the fraction by b/b and then factoring to get the final form.
? is going to be equal to b * (5a + 6).
