b) 2x+5=27

c) 4(5x-3)-4(3-x)-3(12x-4)=96

d) 5(x+1) + 6(x+2) = 9(x+3)

Answer 1

Resposta:

a)x=2

b)x=11

c)x=-9

d)x=5

e)x=3

Answer 2

Explicação passo-a-passo:

a) 10x - 14x = 8 - 16

- 4x = -8

x= -8/-4

x= +2

b) 2x = 27 -5

2x= 22

x= 22/2

x= 11

c) 20x - 12 - 12 +4x - 36x + 12 =96

-12x -12=96

- 12x = 96 +12

- 12x = 108

x= 108/-12

x= -9

d) 5x +5 +6x +12 = 9x +27

11x + 17 = 9x +27

11x - 9x = 27 -17

2x = 10

x= 10/2

x= 5

e) 2x - 6 = - 3x +9

2x +3x = 9 +6

5x = 15

x= 15/5

x= 3
