To solve these equations:

1) (4b-16)/2 = 10
4b - 16 = 210
4b - 16 = 20
4*b = 36
b = 36/4
b = 9

2) (2+x)/7 8 = 72
(2+x)/7 = 72/8
(2+x)/7 = 9
2+x = 97
2+x = 63
x = 63-2
x = 61

3) 35/(15-y/8) = 5
35 = 5(15-y/8)
35 = 75 - 5y/8
5y/8 = 75 - 35
5y/8 = 40
y = 40*8/5
y = 64

4) (t3 + 5)/4 = 8
(t3 + 5) = 84
t3 + 5 = 32
t3 = 32 - 5
t3 = 27
t = 27/3
t = 9

Therefore, the solutions to the equations are:
1) b = 9
2) x = 61
3) y = 64
4) t = 9
