Ha dear.....
Here is your answer..

2x+4x-28-5x
6x-5x-28
x -28

Hence, expression is x-28........

-3r+4 -(2r-3) +8r
-3r +4-2r+3+8r

Hope it will help you my friend.............

Answer 2

$\huge\bf{HEY FRIEND!}$


Part a:-
$2x + 4(x - 7) - 5x$

$= 2x + 4x - 28 - 5x$

$x - 28$

Part b:-

$- 3r + 4 - (2r - 3) + 8r$

$- 3r + 4 - 2r + 3 + 8r$

$3r + 7$

hope it helps u :)
