Answer 1

a)2x+3x-7x+12x=10x

b)13y-2y+(6y-3y)-y=13y

c)(16a+12a+5a)-(31a-22a)=24a

d)-5b+3b-2b+(7b-b+2b)-b=3b

Answer 2

$a)2x + 3x - 7x + 12x = (2 + 3 - 7 + 12) x = 10x$

$b)13y - 2y + (6y - 3y) - y = 13y - 2y + (3y) - y = 13y - 2y + 3y - y = 13y$

$c)(16a + 12a + 5a) - (31a - 22a) = (33a) - 9a = 33a - 9a = 24a$

$d) - 5b + 3b - 2b + (7b - b + 2b) - b = - 5b + 3b - 2b + (8b) - b = - 5b + 3b - 2b + 8b - b = 3b$
