To solve these equations:

1) 234 - y = 220
To isolate y, we can subtract 234 from both sides:

Therefore, the solution for the first equation is y = -14.

2) 72/b + 13 = 19
To solve for b, we first want to isolate the term with b.
Subtract 13 from both sides:
72/b = 19 - 13
72/b = 6

To solve for b, we can cross multiply:
72 = 6b

Divide both sides by 6:
b = 72/6
b = 12

The solution for the second equation is b = 12.
