f) 4 [ ( 3x- 2y ) - ( 4x + 3y )] - [( y-x) - 2 ( 5x- 4y )] =

Answer 1

b) 2a-14b-4b-8b-5a-5b+24b-16a=-19a-7b

c)8x+12y-2y+10x+2y+x-6x+7y=13x+5y

d)2b-c+3-4b-12c+24-6+3c-3b=-5b-10c+21

e)3t-2w-4t-6w=-t-8w

f)4(3x-2y-4x-3y)-(y-x-10x+8y)=12x-8y-16x-12y-y+x+10x-8y=7x-29y

Answer 2

b)  2a - 14b - 4b - 8b + 5a - 5b + 24 b - 16a = -9a - 7b
c) 8x - 12y - 2y + 10x + 2y + x - 6x + 7y = 13x - 5y
d) 2b - c + 3 - 4b - 12c + 24 - 6 + 3c - 3b = -5b - 10c + 27
e) 3t - 2w - 4t + 6w = -t + 4w
f) 12x - 8y + 16x - 12y - y + x + 10x - 8y = 39x - 29y
