B) 4x= -16

C) -2y=0

D) 3y+1=10

E) y/2=-1

F) y/3=3/2

ME AJUDEM A RESPONDER AS CONTAS ​

Answer 1

Explicação passo-a-passo:

2x+4=6

2x=6-4

2x=2

x=2/2

x=>1

4x= -16

x=-16/4

x=>-4

-2y=0

y=-0/2

y=0

3y+1=10

3y=10-1

3y=9

y=9/3

y=3

y/2=-1

y=-1×2

y=-2

y/3=3/2

2y=9

y=9/2

Answer 2

Resposta:

A)

$2x + 4 = 6 \\ 2x = 6 - 4 \\ 2x = 2 \\ x = 1$

B)

$4x = - 16 \\ 4x \div 4 = - 16 \div 4 \\ x = - 4$

C)

$- 2y = 0 \\ - 2y \div ( - 2) = 0 \div ( - 2) \\ y = 0$

D)

$3y + 1 = 10 \\ 3y = 10 - 1 \\ 3y = 9 \\ y = 3$

E)

$\frac{y}{2} = - 1 \\ 2 \times \frac{y}{2} = 2 \times ( - 1) \\ y = - 2$

F)

$\frac{y}{ 3} = \frac{3}{2} \\ 2y = 9 \\ y = \frac{9}{2}$
