[tex]2 \frac{5}{6} + x = 3.5 \div 0.5[/tex]
[tex] \frac{17}{6} + x = \frac{7}{2} \div \frac{1}{2} [/tex]
[tex] \frac{17}{6} + x = \frac{7}{2} \times 2[/tex]
[tex] \frac{17}{6} + x = 7[/tex]
[tex]x = 7 - \frac{17}{6} [/tex]
[tex]x = \frac{25}{6} = 4 \frac{1}{6} [/tex]
[tex]2.7 \div y = 1 \frac{3}{4} - 0.85[/tex]
[tex] \frac{27}{10} \times \frac{1}{y} = \frac{7}{4} - \frac{17}{20} [/tex]
[tex] \frac{27}{10y} = \frac{9}{10} [/tex]
[tex]270 = 90y[/tex]
[tex]90y = 270[/tex]
[tex]y = 3[/tex]
[tex] \frac{z + 6}{3} = 3.4[/tex]
[tex]z + 6 = 10.2[/tex]
[tex]z = 10.2 - 6[/tex]
[tex]z = 4.2[/tex]
[tex] \frac{w - 3}{2} = 4.9 \times \frac{5}{7} [/tex]
[tex] \frac{w - 3}{2} = \frac{49}{10} \times \frac{5}{7} [/tex]
[tex] \frac{w - 3}{2} = \frac{7}{10} \times 5[/tex]
[tex] \frac{w - 3}{2} = \frac{7}{2} [/tex]
[tex]w - 3 = 7[/tex]
[tex]w = 7 + 3[/tex]
[tex]w = 10[/tex]
Mam nadzieję że pomogłam ❤️
