Tolong dijawab ya.......

1. B + 6 = 9
B = 9 - 6
B = 3

2. Y + 7 = 4
Y = 4 - 7
Y = -3

3. Q - 14 = 8
Q = 8 + 14
Q = 22

4. 5q - 4 = -9
5q = -9 + (-4)
5q = -13
Q = -13 : 5
Q = -2,6

5. 6n + 17 = 17
6n = 17 - 17
6n = 0
N = 0 : 6
N = 0

6. 3q + 2 = 2q - 1
3q - 2q = -2 - 1
1q = -3
Q = -3
Maaf klu salah

7.
