Hello Kiddo, You're adding when you should be subtracting.

If Thomas earns $12,000 more than Ping

T = 12,000 + P

(T - 12,000) = P

and He earns $18,000 more than Lydia

T = 18,000 + L

(T - 18,000) = L

how much does Thomas earn?

T + (T - 12,000) + (T - 18,000) = 144,000

3T - 30,000 = 144,000

3T = 144,000 + 30,000

3T = 174,000

T = 58,000
