1) 3n / n-1 - 1 / 3= -40/ 3n - 18
2) 2x / x-2 + 15 / x^2 - 7x + 10 = 3/x-5
im having trouble with these fractional equations . I'd appreciate any help. thanks a lot

First, factor out that denominator on the RHS.
Now, to simplify this equation you will want to multiply both sides by the common denominator. In this case the denominators are n - 1, 3, and 3(n - 6). What is the common denominator of these three expressions?

Now factor (x^2 - 7x + 10)
