Question

Determine o valor de X:
X+3/x = 1 +1-x/2x

Answer 1

Resposta:

$\frac{x + 3}{x} = 1 + \frac{1 - x}{2x} \\ \\ \frac{x + 3}{x} - \frac{1 - x}{2x} = 1 \\ \\ \frac{2 \times (x + 3) - (1 - x)}{2x} = 1 \\ \\ \frac{2x + 6 - 1 + x}{2x} = 1 \\ \\ \frac{3x + 5}{2x} = 1 \\ \\ 3x + 5 = 2x \\ 3x = 2x - 5 \\ 3x - 2x = - 5 \\ x = - 5$
