Question

решите уравнение 1)975*(y-361)=14625     2)(30142+z):876=49      3)51815:(p-975)=1205     3)13x+15x-24=60       4)18y-7y-10=12

Answer 1

1) 975 y = 14625 + 351975
975 y = 366600
y = 376
3) 13x+15x-24=60
28x=84
x = 3
4)18y-7y-10=12
11y=22
y=2
2) (30142+z)/876 = 49
30142+z=42924
z=12782

Answer 2

1)=975y-351975=14625
975y=14625+351975
975y=366600
y=366600:975
y=376
