To solve these equations:

1) 321 - x = 4502
Subtract 321 from both sides
-x = 45020 - 32
-x = 4469
Divide by -1 to solve for x
x = -44699

2) 4 - x = -1
Add x to both sides
4 = -13 +
x = 4 + 1
x = 17

3) 6122 - y = -2005
Add y to both sides
6122 = -20050 +
y = 6122 + 2005
y = 26172

4) 3 - y = 7
Add y to both sides
3 = 72 +
y = 3 - 7
y = -69

Therefore, the solutions are
1) x = -4469
2) x = 1
3) y = 2617
4) y = -69
