- (2,5т - 3 3/4 п - 1,2т ) = - (1,3т - 3 3/4 п ) = - 1,3т + 3 3/4 п
если т= 3 1/3 , п= - 1 1/5
-1,3 * 3 1/3 + 3 3/4 * (- 1 1/5 ) =
= - 13/10 * 10/3 + 15/4 * (- 6/5) =
= - 1 + (- 9/2) = - 1 + (-4,5) = - 5,5

zhenyaM2002 я ошибся в выражении 2 строка (-13/10) * 10/3 = - 13/3 => - 13/3 + (-9/2) = -26/6 - 27/6 = -53/6 = -8 5/6. Извините.
