Question

2x-3/5=9/10. x+3/2=3x-2/7. /это дробь

Answer 1

$2x - \frac{3}{5} = \frac{9}{10} \\ \\ 2x = \frac{9}{10} + \frac{3}{5} \\ \\ \frac{9 + 6}{10} \\ \\ \frac{15}{10} = \frac{3}{2} \\ \\ 2x = \frac{3}{2} \div 2 \\ \\ x = 0.75 \\ \\ \\ \\ x + \frac{3}{2} = 3x - \frac{2}{7} \\ \\ x - 3x = - \frac{2}{7} - \frac{3}{2} \\ \\ - 2x = - \frac{25}{14} \div - 2 \\ \\ x = \frac{25}{28}$
