Resolva a Equação 3x – 4x + 8x – 2(7x+3)=2-4(x-2x)
a) -8
b) 8
11
c) 7
9
d) −
8
11
e) 1
2

Answer 1

3x – 4x + 8x – 2(7x+3) = 2-4(x-2x)

-x + 8x - 14x - 6 = 2 - 4x + 8x

7x - 14x - 6 = 2 + 4x

-7x - 4x = 2 + 6

-11x = 8

x = 8/-11

ALTERNATIVA D !!!

Bons Estudos!!!

Answer 2

Resposta:

-8/11

Explicação passo-a-passo:

3x – 4x + 8x – 2(7x+3)=2-4(x-2x)

3x - 4x + 8x -14x -6 = 2 -4x + 8x

3x - 4x + 8x - 14x + 4x -8x = 2 + 6

-11x = 8

x = -8/11
