Решите пожалуйста....
1) -10y - 64 = -6y
-10y + 6y = 64
-4y = 64
-y = 16
y = -16
2) 9m - 8 = 6m + 7
9m - 6m = 7 + 8
3m = 15
m = 5
3)6x + 10 = 5x + 15
6x - 5x = 15 - 10
x = 5
4)16m - 5 = 15m - 10
16m - 15m = -10 + 5
m = -5
5)8 - 5n = 10 - 4n
-5n + 4n = 10 - 8
-n = 2
n = -2
6)18 = 3y + 3
-3y = 3 - 18
-3y = -15
y = 5
