Answer:
Step-by-step explanation:
[tex]\sf \left(2x+\cfrac{1}{2}\right)+\left(8x-2\cfrac{1}{2}\right)[/tex]
We'll need to convert the mixed number 2 1/2 to improper fraction.
[tex]\sf \left(2x+\cfrac{1}{2}\right)+\left(8x-\cfrac{5}{2}\right)[/tex]
Simplify...
[tex]\sf 2x+\cfrac{1}{2}+8x-\cfrac{5}{2}[/tex]
Add similar elements.
[tex]\sf 10x+\cfrac{1}{2}-\cfrac{5}{2}[/tex]
[tex]\sf 10x+\cfrac{-4}{2}[/tex]
Divide numbers..
[tex]\sf 10x-2[/tex]
