Question

Simplifique as expressões algébricas:


a) 9m + 7 + 10m=

b) 4.(x-1) + 2 . (x + 1)=

c) -2.(2x-4)-5.(-2x + 10)=

d) -3/2x + 1/3a + 1/3x - 1/2a=

e) 2p/3 - y/2 - 5p/8 + y​

Answer 1

Resposta:

a) 9m + 7 + 10m = 19m + 7

b) 4x-4+ 2x + 2 = 6x-2

c) 4x-8+10x - 50 = 14x - 58

d) -3x/2 + a/3 + x/3 - a/2

mmc = 6

-9x/6+2a/6+ 2x/6 - 3a/6 = -7x/6 - a/6

e) incompleta ( 4 numeradores e 3 divisores)
