1. Do the opposite of addition (subtraction)

$4x - 10 - (-5x + 20)$

2. Change this equation (-5x - 20) into a positive (5x + 20)

$4x - 10 + 5x - 20$

$9x - 10$

Subtract them, just like you added:
4x + 10 - (-5x +20)
The minus turns (-5x + 20) into the opposite, or 5x - 20
4x + 10 + 5x - 20
9x - 10
I really hope this helps.
