Решение/ :
1) x + 5,95 = 761,5;
x = 761,5 - 5,95;
x = 755,55.
__________
: 755,55.
2) x - 74,85 = 338,563;
x = 338,563 + 74,85;
x = 413,413.
__________
: 413,413.
3) 64,021 - x = 9,7;
x = 64,021 - 9,7;
x = 54,321.
или
- x = 9,7 - 64,021;
- x = - 54,321 | × (- 1)
x = 54,321.
__________
: 54,321.
4) x - 84,52 = 218,48;
x = 218,48 + 84,52;
x = 303.
___________
: 303.
