# Adding and Subtracting Rational Expressions

posted by .

Iwouldhighly appreciate it if someone could solve these forme.I think I typed themout correctly. What I'm looking at,for instance,the first one,is displayed 5n over 3 times 4n over 3
1.(5n/3)- (4n/3)
2.(3x/10)+(9x/10)
3.(n-2/n+4)+(8/[n+4])
4.(5m+8/[m-1]) - (m-3/[m-1])
5.(x^2/[x-1]) - (1/[x-1])
6.(4x+y/[2x+3y])-(2x -2y/[2x+3y])
7.(x^2+3x+2/[x^2-16] + (3x++6/[x^2-16])
8.7/(x-5) - (2+x/[x-5])

First, "(5n/3)- (4n/3)" is not "5n over 3 times 4n over 3."

If the fractions have the same denominator, just do the required operations in the numerator.

(5n/3)- (4n/3) = n/3

Use the same principle for the remaining problems.

I hope this helps. Thanks for asking.
