Question

(7x - 3) - (1 - 2x) = 4 - 3x.

Answer 1

Resposta:

Explicação passo-a-passo:

(7x - 3) - (1 - 2x) = 4 - 3x

7x - 3 - 1 + 2x = 4 - 3x

7x + 2x + 3x = 4 + 3 + 1

12x = 8

  x = 8/12

  x = 2/3

• Bom... vamos lá, baby demon!

$(7x - 3) - (1 - 2x) = 4 - 3x \\ 7x - 3 - (1 - 2x) = 4 - 3x \\ 7x - 3 - 1 + 2x = 4 - 3x \\ 9x - 3 - 1 = 4 - 3x \\ 9x - 4 = 4 - 3x \\ 9x - 4 + 3x = 4 \\ 9x + 3x = 4 + 4 \\ 12x = 4 + 4 \\ 12x = 8 \\ 12x \div 12 = 8 \div 12 \\ x = 8 \div 12 \\ \\ x = \frac{8}{12} \\ \\ x = \frac{2}{3}$
