Question

Resolva as equações
A) Y=3x-2
B) Y= -4+3
C) Y=2,3x+12
D) Y= x-1

Answer 1

Resposta:

Explicação passo-a-passo:

A)

Y = 3x - 2

0 = 3x - 2

2 = 3x

3x = 2

x = 2/3

______________

B)

Y= -4x +3

0 = - 4x + 3

4x = 3

x = 3/4

____________

C)

Y=2,3x + 12

0 = 2,3x + 12

- 12 = 23x/10

- 12.10 = 23x

- 120 = 23x

23x = - 120

x = - 120/23

______________

D)

Y= x-1

0 = x - 1

1 = x

x = 1
