me ajudem pfv​

Answer 1

Resposta:

a)

$x = 0$

b)

$x = \frac{5}{48}$

Explicação passo-a-passo:

A)

$4x + \frac{1}{3} + \frac{2}{3} - 4 \times \frac{ x}{3} + 1$

$4x + 1 - 4 \times \frac{x}{3} + 1$

$4x + 1 = \frac{4x}{3} + 1$

$4x = \frac{4x}{3}$

$3x = x$

$3x - x = 0$

$2x = 0$

$x = 0$

B)

$3x - \frac{7}{12} + x - \frac{1}{8} - 2x - \frac{3}{6}$

$4x - \frac{7}{12} - \frac{1}{8} = 2x - \frac{3}{6}$

$4x - \frac{17}{24} - 2x - \frac{3}{6}$

$4x - \frac{17}{24} - 2 x - \frac{1}{2}$

$4x - 2x - \frac{17}{24} = - \frac{1}{2}$

$4x - 2x = - \frac{1}{2} + \frac{17}{24}$

$2x = - \frac{1}{2} + \frac{17}{24}$

$2x = \frac{5}{24}$

$x = \frac{5}{48}$
