Александра Чернова · Answer 1

1) (х + 3,8) - 5,4 = 72,85;

x + 3.8 - 5.4 = 72.85;

x - 1.6 = 72.85;

x = 72.85 + 1.6;

x = 74.45.

2) (х - 23,58) + 37,6 = 150,78;

x - 23.58 + 37.6 = 150.78;

x + 14.02 = 150.78;

x = 150.78 - 14.02;

x = 136.76.

3) 10,36 + (х - 56,051) = 120,309;

10.36 - 56.051 + x = 120.309;

x - 45.691 = 120.309;

x = 120.309 + 45.691;

x = 166.

4) 35,56 - (х + 12,07) = 18,49;

35.56 - x - 12.07 = 18.49;

23.49 - x = 18.49;

x = 23.49 - 18.49;

x = 5.
