[tex]x+(-2\frac{1}{4})= -\frac{2}{5}[/tex]

[tex]x-2\frac{1}{4} = -\frac{2}{5}[/tex]

[tex]x= -\frac{2}{5} +2\frac{1}{4}[/tex]

[tex]2\frac{1}{4}-\frac{2}{5} =2\frac{5}{20} -\frac{8}{20} =1\frac{25}{20} -\frac{8}{20} =1\frac{17}{20}[/tex]

[tex]x=1\frac{17}{20}[/tex]

Ответ: [tex]x=1\frac{17}{20}[/tex]
