: I have the same types of probs as Jalomy can any one help me solve for x
: (3*x+25/(x+7))-5= 3/x
:
: (2*x-1/x)+1= 4/(x+1)
:
: 4/x - 3/(x+1)=7
Let's take the first one as an example:
(3*x+25/(x+7))-5= 3/x
To clean it up, multiply both sides by the lowest common denominator, which in this case is x*(x+7):
x*(x+7)*[(3*x+25/(x+7))-5] = (3/x)*x*(x+7)
Now multiply that out and CAREFULLY combine like terms & you should end up with something much more manageable. Give it a try.
The same technique works for the other ones.
