Question

(2 - 5x)/4 - (2x + 4)/4 = x + 2

Answer 1

Explicação passo-a-passo:

$\frac{2 - 5 \times }{4} - \frac{2 \times + 4}{4} = \times + 2$

$\frac{(2 - 5 \times ) \times 4}{4} - \frac{(2 \times + 4) \times 4}{4} = \times x \: 4$

$(2 - 5 \times ) - (2 \times + 4) = \times x \: 4 + 2 \times 4$

$(2 - 5 \times ) - 2 \times - 4 = 4 \times + 2 \times 4$

$(2 - 5x) - 2 \times - 4 = 4 \times + 8$

$2 - 5 \times - 2 \times - 4 = 4 \times + 8$

$- 2 - 7 \times = 4 \times + 8$

$- 7 \times - 4 \times = 8 + 2$

$- 11 \times = 8 + 2$

$- 11 \times = 10$

$\times = - \frac{10}{11}$

desculpa qualquer erro!
