: I have a question where i have to put over a common dominator and simplify. There is a similar question by somebody further down. I have looked at that but i am having trouble with this one.
: 2x/3x-1 + 5/7-2x
: Any help appreciated, Thanks
************************************
The problem should be posted as:
2x/(3x-1) + 5/(7-2x)
How would you evaluate:
2/7 + 5/9
= 2*9/(7*9) + (5*7)/(9*7)...[make denominators equal to LCD]
=(18)/(63) + (35)/(63)
=[(18) + (35)] / (63
= 53/63
Follow the "exact" same route ... if you get stuck show us your work. We'll try to help...
