Question

REDUZA OS TERMOS SEMELHANTES (CESEC)

Answer 1

a) 8a + 2a = 10a

b) 4a + a - 7a = -2a;

c) 7x - 5x = 2x

d) 7x - 5x + 3x = 5x

e) 6ab - 2b + 4a - 6b + ab = 4a - 2b - 6b + 6ab + ab = 4a - 8b + 7ab

f) 0,7x - 0,5y + 0,3x - 1,4y + y = 0,7x + 0,3x - 0,5y -1,4y + y = 1x - 0,9y

g) 6x + ( 2x - 4 ) - 2 = 6x + 2x - 4 - 2 = 8x - 6

h) 7y - 8 - ( 5y - 3 ) = 7y - 5y - 8 - 3 = 2y - 11
