Question

5(×+2)-13=2(3×-1) me ajuda

Answer 1

Resposta:

Olá,

» x = -1

5(x + 2) - 13 = 2(3x - 1)

5x + 10 - 13 = 2(3x - 1)

5x - 3 = 2(3x - 1)

5x - 3 = 6x - 2

5x - 3 + 3 = 6x - 2 + 3

5x = 6x + 1

5x - 6x = 6x + 1 - 6x

-x = 1

-x/-1 = 1/-1

x = -1

» Podemos realizar de outro modo:

5(x + 2) - 13 = 2(3x - 1)

5x + 10 - 13 = 2(3x - 1)

5x - 3 = 2(3x - 1)

5x - 3 = 6x - 2

5x - 6x = -2 + 3

-x = -2 + 3

-x = 1

-x × (-1) = 1 × (-1)

x = 1 × (-1)

x = -1
