[tex]x =156842\frac{2}{19}[/tex]

Объяснение:

Решаем уравнение х - 5(х ÷ 100) = 149000 —

[tex]x - 5\times(\frac{1}{100} x)=149000\\\\ x-5\times\frac{1}{100} x=149000\\ \\ x-\frac{5}{1} \times\frac{1}{100} x=149000\\ \\ x - \frac{1}{1} \times\frac{1}{20} x=149000\\ \\ x-\frac{1}{20} x=149000\\ \\ \frac{20}{20} x-\frac{1}{20} x=149000\\ \\ \frac{19}{20} x=149000\\ \\ (\frac{19}{20} x)\times \frac{20}{19} =(149000)\times\frac{20}{19} \\ \\ x = \frac{2980000}{19} =156842\frac{2}{19}[/tex]
