Answer 1

$2 \frac{2}{3} x - 6.7x + 5.6x = \frac{47}{50} \\ 2 \frac{2}{3} x - 1.1x = \frac{47}{50} \\ 2 \frac{2}{3} x- 1 \frac{1}{10} x = \frac{47}{50} \\ 2 \frac{20}{30} x - 1 \frac{3}{30} x = \frac{47}{50} \\ 1 \frac{17}{30} x = \frac{47}{50} \\ x = \frac{47}{50} \div 1 \frac{17}{30} \\ x = \frac{47 \times 30}{50 \times 47} \\ x = \frac{3}{5} \\ x = 0.6$
