Answer 1

Explicação passo-a-passo:

a)

8x-3=4x-9

8x-4x=-9+3

4x=-6

x=-6/4

x=(-6÷2)/(4÷2)

x=-3 /2

b)

13x-26=0

13x=26

x=26/13

x=2

c)

5x+3.(2x+4)+x= 0

5x+6x+12+x=0

11x+x=-12

12x=-12

x=-12/12

x=-1

Answer 2

Resposta:

Explicação passo-a-passo:

A) 8x-3=4x-9

8x - 4x = -9 +3

4x = - 6

X = - 6/4

X = - 3/2

b)13x-26=0

13x= 0 + 26

X = 26/ 13

X = 2

c)5x+3 (2x+4)+x= 0

5x + 6x + 12 + x = 0

12 x = - 12

X = - 12/12

X = - 1
