Step-by-step explanation:
<u>Step 1: Define</u>
1/3x = -4/5
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Division Property of Equality] Divide 1/3 on both sides: x = -12/5
Since none of these are like terms, none of these could be added together. All you need to do is to order these by alphabetical order. Therefore, the simplified form of this expression is an+bn+7a+7b
Answer:

Step-by-step explanation:
Your question is:
![\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}](https://tex.z-dn.net/?f=%5Cfrac%7B8u%7D%7Bu%5E2-18u%2B81%7D%20-%5Cfrac%7B72%7D%7Bu%5E2-18u%2B81%7D)
Then, the above formula equate:
![\frac{8u-72}{u^2-18u+81}](https://tex.z-dn.net/?f=%5Cfrac%7B8u-72%7D%7Bu%5E2-18u%2B81%7D)
Factor out 8 from the numerator we get:
![\frac{u-9}{u^2-18u+81}](https://tex.z-dn.net/?f=%5Cfrac%7Bu-9%7D%7Bu%5E2-18u%2B81%7D)
Factorization of the denominator:
![\frac{u-9}{(u-9)^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bu-9%7D%7B%28u-9%29%5E2%7D)
Simplifying the numerator and the denominator by (u-9) we get:
