Даю 90 баллов.

б) 0,4b +0,8 = 0,9b - 2,7

в) [tex]1 - \frac{a}{7} = \frac{a}{14} - 0,25a[/tex]

г) [tex]3 - ( \frac{2}{9}m + \frac{1}{6}) = \frac{m}{3} + 1,5[/tex]

д) 2,6z - 0,2(3z -9) = -0,5(2z +6)

е) [tex] \frac{5}{12}(c -3) - \frac{1}{6}(2c - 7) = 2[/tex]

ж) [tex] \frac{-3}{9-4a} = \frac{40}{200} [/tex]

з) [tex] \frac{1-2b}{4} = \frac{0,8}{0,5} [/tex]

и) [tex] \frac{5+3x}{12} = \frac{4x- 3}{18} [/tex]

k) [tex] \frac{0,9}{7+5y} = \frac{0,2}{y - 4} [/tex]
