Answer 1

Ответ:

5,6x-1,2х=0,68

4,4х=0,68

х=0,68/4,4

х=0.154

Answer 2

$5.6x - 1.2 = 0.68 \\ 5.6 = 0.68 + 1.2 \\ 5.6 x = 1.88 \\ 5.6x \div 5.6 = 1.88 \div 5.6 \\ x = \frac{47}{25} \div \frac{28}{5} \\ x = \frac{47}{25} \times \frac{5}{28} \\ x = \frac{47}{5} \times \frac{1}{28} \\ otvet \\ x = \frac{47}{140}$
