Question

Quanto fica 3x-3/4=4/3

Answer 1

$\frac{3x -3}{4} = \frac{4}{3} \\ 3(3x - 3) = 4.4 \\ 9x - 9 = 16 \\ 9x = 16 + 9 \\ 9x = 25$

$x = \frac{25}{9}$

Answer 2

$3x - \frac{3}{4} = \frac{4}{3}\\\\3x = \frac{4}{3} + \frac{3}{4}\\\\3x = \frac{16+9}{12}\\\\3x = \frac{25}{12}\\\\x = \frac{25}{12*3}\\\\x = \frac{25}{36}$

R: x = 25/36 ou 0,69444...
