Here are the solutions to the problems:

1)

Simplify the expression by removing the parenthesis.
$-5+2+(-8)-9 = -5+2-8-9$
Perform the additions and subtractions from left to right.
$-5+2-8-9 = -3-8-9$ $-3-8-9 = -11-9$ $-11-9 = -20$
The student's partial work $-5+2-8-9$ is correct.
$\boxed{-20}$
2)
Perform the additions and subtractions from left to right.
$2-9+6-10 = -7+6-10$
Continue the operations.
$-7+6-10 = -1-10$ $-1-10 = -11$ $\boxed{-11}$
3)
Perform the additions and subtractions from left to right.
$-3-5+4 = -8+4$
Complete the operation.
$-8+4 = -4$ $\boxed{-4}$
4)
Perform the subtractions from left to right.
$8-10-4 = -2-4$
Complete the operation.
$-2-4 = -6$ $\boxed{-6}$
5)
Perform the operation inside the parenthesis.
$(-4+3) \times 4 = (-1) \times 4$
Perform the multiplication.
$(-1) \times 4 = -4$ $\boxed{-4}$
6)
Perform the operation inside the parenthesis.
$(3-7) \times (-2) = (-4) \times (-2)$
Perform the multiplication.
$(-4) \times (-2) = 8$ $\boxed{8}$
7)
Perform the operation inside the parenthesis.
$(10-3) \times (-6) = (7) \times (-6)$
Perform the multiplication.
$(7) \times (-6) = -42$ $\boxed{-42}$
8)
Perform the operation inside the parenthesis.
$(-2-2) \times 3 = (-4) \times 3$
Perform the multiplication.
$(-4) \times 3 = -12$ $\boxed{-12}$

Solve the following equations: -5+2+(-8)-9, 2-9+6-10, -3-5+4, 8-10-4, (-4+3)x4, (3-7)x(-2), (10-3)x(-6), (-2-2)x3
