Question

responda : 5(3-x)-4x=18

Answer 1

Resolução!

5 ( 3 - x ) - 4x = 18

15 - 5x - 4x = 18

- 5x - 4x = 18 - 15

- 9x = 3 * (-1)

9x = - 3

X = - 3/9 ÷ 3

X = - 1/3

Answer 2

Olá

5(3 - x) - 4x = 18

15 - 5x - 4x = 18

- 9x = 18 - 15

- 9x = 3==>(× - 1)

9x = - 3

x = - 3/9 ÷ 3

x = - 1/3

Resposta: x = - 1/3

Bons estudos.
