Question

2x-3/5=9/10. x+3/2=3x-2/7. /это дробь

Answer 1

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