Question

x:1,3-2,14=3,66 помогите решить

Answer 1

$x \div 1.3 - 2.14 = 3.66 \\ x \div \frac{13}{10} - \frac{107}{50} = \frac{183}{50} \\ x \times \frac{10}{13} - \frac{107}{50} = \frac{183}{50} \\ \frac{10}{13} x - \frac{107}{50} = \frac{183}{50} \\ 500x - 1391 = 2379 \\ 500x = 2379 + 1391 \\ 500x = 3770 \\ x = \frac{3770}{50} = 7 \frac{27}{50} = 7.54$

Answer 2

х:1,3-2,14=3,66
х:1,3=3,66+2,14
х:1,3=5,8
х=5,8*1,3
х=7,54
