Решите уравнение:
1) х : 16 = 4759 + 1441;
2) у : 27 = 2467 − 1867;
3) 13 600 : z = 3876 − 3851;
4) (2865 + k) * 125 = 542875.
x : 16 = 4759 + 1441 = 6200
x = 6200 * 16 = 99200
у : 27 = 2467 − 1867 = 600
у = 600 * 27
у = 16200
13600 : z = 3876 − 3851 = 13600
z = 13600 : 25 = 544
(2865 + k) − 125 = 542875
2865 + k = 542875 : 125 = 4343
k = 4343 − 2865 = 1478
