Question

Помогите пожалуйста,856 номер

Answer 1

1) 16x -170 +14x - 330 = 85x + 1400 - 56x + 58
30x - 29x = 500 + 1458
x = 1958

2) 1350 + 5y + 500 = 15y - 150 - 589
15y - 5y = 1850 + 739
10y = 2589
y = 258,9

3) 9z - 657 - 8z - 3000 = 238 - 11z + 77
z + 11z = 315 + 3657
12z = 3972
z = 331

4) 17x + 221 - 19x + 399 +249 = 125x - 1325 -21x -1728
104x + 2x = 3053 + 869
106x = 3922
x = 37

5) 8y - 2600 -17y - 15980 = 6576 - 6y - 94y + 1598
100y - 9y = 8174 + 18580
91y = 26754
y = 294

6) 85z - 27 -19 - 19z = 43 - 43z + 91 + 91z
66z - 48z = 134 + 46
18z = 180
z = 10
