You can solve this by isolating the variable.

1.

30 + a = 40

You can isolate a by subtracting 30 from each side

30 + a - 30 = 40 - 30

a = 10

2.

500 + b = 200

Subtract 500 from each side

500 + b - 500 = 200 - 500

b = -300

3.

-1 + c = -2

Add 1 to each side

-1 + c + 1 = -2 + 1

c = -1

4.

d + 3567 = 0

Subtract 3567 from each side

d + 3567 - 3567 = -3567

d = -3567
