1. 10y-4y+13y-y+2y
2. 4(5x-2)-(x-9)+5(2x-9)

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

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

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

(10y-4y+13y-y+2y)

(10-4+13-1+2)y

(20)y

20y

Answer: 20y

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

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

Answer: 29x - 44
