Answer: The simplified expression is: " -2y + 19 " .
________________________________
Explanation:
Simplify this given expression: " 10 - 6y + 4y + 9 " .
Start with combining the "like terms:
+ 10 + 9 = + 19 ;
- 6y + 4y = - 2y ;
Now write the simplified expression:
" -2y + 19 " .
Note that the variables come first; in order of degrees, then the numbers, if any.
Hope this helps!
Best of luck to you in the "Brainly community" and in your future academic pursuits!
