Question

Resolva a seguinte fração: $x-4 - \frac{x+4}{3} = 0$

Answer 1

$x - 4 - \frac{x + 4}{3} = 0 \\\\ x - 4 = \frac{x + 4}{3} \\\\ 3 \cdot (x - 4) = x + 4 \\\\ 3x - 12 = x + 4 \\\\ 2x = 16 \\\\ \boxed{x = 8}$

Answer 2

Oie, Td Bom?!

$x - 4 - \frac{x + 4}{3} = 0$

$3x - 12 - (x + 4) = 0$

$3x - 12 - x - 4 = 0$

$2x - 16 = 0$

$2x = 16$

$x = \frac{16}{2}$

$x = 8$
