Simplify 4x/9 + x-10/9 Show work pleasee(:

OpenStudy (anonymous):

since they have common denominators you would just add the numerators together.

OpenStudy (anonymous):

So... it'd be 5x-10/9?

OpenStudy (anonymous):

yupp :D

OpenStudy (anonymous):

Yayy(: lol

OpenStudy (anonymous):

Could you help me with another one that doesn't have a common denominator?

OpenStudy (anonymous):

sure!

OpenStudy (anonymous):

3/x + 3/x-11

OpenStudy (anonymous):

multiply the equation on the left by (x-11) and multiply the one on the right by x to get common denominators :)

OpenStudy (anonymous):

so the denominators would be x^2-11?

OpenStudy (anonymous):

x^2-11x, remember to distribute the x to the 11 as well :)

OpenStudy (anonymous):

Ohh okay! Thank you(:
