Question

Simplifique as operações b) 4 • ( x - 1 ) +2 • ( x + 1 ) =
c) -2•(2×-4) -5 (-2× + 10 ) =
D) -3/2× + 1/3a + 1/3x - 1/2a =
E ) 2p/3 - y/2 - 5p/8 + y =

Answer 1

Resposta:

B)4x-4+2x+2

4x+2x+2-4

6x-2

C)-4+8+10x-50

10x-4+8-50

10x-46

Answer 2

Resposta:

Explicação passo-a-passo:

b) 4 • ( x - 1 ) +2 • ( x + 1 ) =

4x-4+2x+2= 6x-2

c) -2•(2×-4) -5.(-2× + 10 ) =

-4x-8-10x+50

-14x – 42

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

mmc = 6  

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

-7x/6 - a/6  

e ) 2p/3 - y/2 - 5p/8 + y =

mmc = 24 e 2

16p/24-y/2-15p/24+y

1p/24 -y/2
