Explicație pas cu pas:
[tex] - \frac{10}{11} x + 1 = \frac{17}{22} \\ [/tex]
[tex] - \frac{10}{11} x = \frac{17}{22} - {}^{22)} 1 \\ [/tex]
[tex] - \frac{10}{11} x = \frac{17}{22} - \frac{22}{22} \\ [/tex]
[tex] - \frac{10}{11} x = - \frac{5}{22} \\ [/tex]
[tex]x = - \frac{5}{22} : \Big( - \frac{10}{11}\Big) = \frac{ \not5}{ \not22} \cdot \frac{ \not11}{ \not10} = \frac{1}{2} \cdot \frac{1}{2} = \boxed{\frac{1}{4}} \\ [/tex]
_______________
[tex]x + \frac{7}{8} = \frac{3}{4} \\ [/tex]
[tex]x = \frac{ {}^{2)} 3}{4} - \frac{7}{8} = \frac{6}{8} - \frac{7}{8} = \boxed{ - \frac{1}{8} } \\ [/tex]
_______________
[tex]x - \frac{2}{3} \cdot \frac{5}{4} = \frac{5}{12} \\ [/tex]
[tex]x - \frac{10}{12} = \frac{5}{12} \\ [/tex]
[tex]x = \frac{5}{12} + \frac{10}{12} = \frac{15 {}^{(3} }{12} = \boxed{ \frac{5}{4} } \\ [/tex]
