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) 19m + 7

b) 6x - 2

c) 6x - 42

d) - 7x/6 - a/6

e) p/24 + 12y/24

Explicação passo a passo:

a) 19m + 7

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

c) - 4x + 8 + 10x - 50 = + 6x - 42

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

e) 16p - 12y - 15p + 24y = p/24 + 12y/24
