Question

3 x sobre 4 menos 2 sobre 3 = x - 5 sobre 2

Answer 1

$\frac{3x}{4} - \frac{2}{3} = \frac{x - 5}{2}$
MMC =12

$12 \times \frac{3x}{4} - 12 \times \frac{2}{3} = 12 \times \frac{(x - 5)}{2} \\ 3 \times 3x - 4 \times 2 = 6 \times (x - 5)$
9x-8=6x-30
9x-6x=-30+8
3x=-27
x=-27/3
x=-9
$x = - 9$
