Question

4х-1целая 4 пятых=5,4

Answer 1

Ответ:

$4x - 1 frac{4}{5} = 5.4$

$4 x = 1 frac{4}{5} + 5.4$

$4x = 7.2$

$x = 7.2 div 4$

$x = 1.8$

Ответ: 1.8

Answer 2

Ответ:

4x - 1$frac{4}{5}$ = 5,4;

5 * 4x - $frac{9}5}$ * 5 = 5,4 * 5;

20x - 9 = 27;

20x = 27 + 9;

20x = 36;

x = 36/20;

x = 1,8;
