Question

Реши уравнение:
74,6−(t−0,38)=31 .

Answer 1

74.6-(т-0,38)=31

т-0,38=74,6-31

т=43,6+0,38

т=43,98

Ответ:43,98

Answer 2

$\displaystyle \tt 74,6-(t-0,38)=31\\\displaystyle \tt 74,6-t+0,38=31\\\displaystyle \tt 74,98-t=31\\\displaystyle \tt -t=31-74,98\\\displaystyle \tt -t=-43,98\\\displaystyle \tt \bold{t=43,98}$
