Zad 5
[tex]a)a - 1 \frac{2}{3} = 7 \frac{2}{3} [/tex]
[tex]a - \frac{5}{3} = \frac{23}{3} [/tex]
[tex]a = \frac{23}{3} + \frac{5}{3} [/tex]
[tex]a = \frac{28}{3} = 9 \frac{1}{3} [/tex]
[tex]b) - 4 \frac{3}{4} - b = 1 \frac{1}{4} [/tex]
[tex] - \frac{19}{4} - b = \frac{5}{4} [/tex]
[tex] - b = \frac{5}{4} + \frac{19}{4} [/tex]
[tex] - b = 6[/tex]
[tex]b = - 6[/tex]
[tex]c)5 \frac{5}{6} + x = 8 \frac{1}{6} [/tex]
[tex] \frac{35}{6} + x = \frac{49}{6} [/tex]
[tex]x = \frac{49}{6} - \frac{35}{6} [/tex]
[tex]x = \frac{7}{3} = 2 \frac{1}{3} [/tex]
Mam nadzieję że pomogłam ❤️
