решите уравнение : 1) x-(-1 23)=-4 56 2) t-2 47=-3 521

23x=-4 56
x=-4 56 : 23
x=-296 * 32
x= -294 = -7,25

1) х - (-1 2/3) = -4 5/6
x + 1 2/3 = -4 5/6
x = -4 5/6 - 1 2/3
x = -29/6 -5/3
x= -29/6 -10/6
x= -39/6 = -6 3/6= -6 1/2

2)t - 2 4/7 = -3 5/21
t = -3 5/21 + 2 4/7
t = - 68/21 + 18/7
t= -68/21 + 54/21
t = -14/21
t= -2/3
