4b + 16 = 35
4b = 19
b =
7.
105 = 7c + 28
7c = 105 - 28
7c = 77
c = 11
8.
8c = 11c - 33
11c - 8c = 33
3c = 33

56 = 5k - 10
5k = 66
k =
12.
7c + 7 = 4c - 8
7c - 4c = -15
3c = -15
c = -5
13.
v =
14.
9n = 42
n =
15.
3b +39 = -10b
13b = -39
b = -3
16.
21b = 3b - 12
21b - 3b = -12
18b = -12
b = -
17.
8x + 16 = 6x - 18
8x - 6x = -18 - 16
2x = -34
