Solving Equations with Rational Expressions
posted by Mike .
Can someone please show me how to solve these for me?
5/(y2)=y+2
(x/3)(2/3)=(1/y5)
(y+2)/7=1(y5)
(x^2)/(x4)7/(x4)=0
x^2/(x+3)5/(x+3)=0
I assume that your second equation has y as a typo. I will use that as an example.
(x/3)(2/3)=(1/x5)
Multiply both sides by 3. I will also assume that (1/x5) is the same as (1/x)5 rather than 1/(x5).
x2=3/x15
Get the x terms on one side and the numerical terms on the other by adding 2 and subtracting 3/x from both sides.
x3/x=17
Multiply both sides by x.
x^23=17x
x^217x3=0
Unfortunately, I cannot carry the process further. However, it should make the process clear.
I hope this helps. Thanks for asking.
