*I assume you need to expand & simplify the expression.

First: eliminate parenthesis - use Distribution.

-7(8x) - 7(-2y) - 5(-x) - 5(4y)
-56x - (-14y) - (-5x) - 20y
-56x + 14y + 5x - 20y

Sec: combine "like" terms.

-56x + 5x + 14y - 20y
- 51x - 6y

P.S. the expression doesn't need to be factored, unless your teachers asks you to do so.

-7(8x-2y) - 5(-x +4y)= -56x +14y +5x -20y =

-51x - 6y = 3(17x -2y)

-7(8x-2y) - 5(-x+4y) =
-56y + 14y + 5x - 20y =
-62y + 5x
