2. 4(5x-2)-(x-9)+5(2x-9) 


----------------------------------------------------------------------------


1. 10y-4y+13y-y+2y


10y-4y+13y-y+2y

2. 4(5x-2)-(x-9)+5(2x-9) 


4(5x-2)-(x-9)+5(2x-9) 


4(5x-2)-1(x-9)+5(2x-9) 


4(5x)+4(-2)-1(x)-1(-9)+5(2x)+5(-9) ... distribute


20x-8-x+9+10x-45


(20x-x+10x)+(-8+9-45)


(20-1+10)x+(-8+9-45)


(29)x+(-44)


29x - 44
