Пошаговое объяснение:
1)
9 - 4y = -5y
-4y + 5y = -9
y = -9
3)
2x + 4 = 6
2x = 6 - 4
2x = 2
x = 2 : 2
x = 1
5)
-5m + 24 = m
m + 5m = 24
6m = 24
m = 24 : 6
m = 4
12a - 1 = -a + 25
12a + a = 25 + 1
13a = 26
a = 26 : 13
a = 2
8 + 3b = -7 + 2b
3b - 2b = -7 - 8
b = -15
3y - 3 = 5 - y
3y + y = 5 + 3
4y = 8
y = 8 : 4
y = 2
