Answer:

Andrew has 30 goldfish and Todd has 10 goldfish

Explanation:

Lets call A the number of goldfish Andrew has and T the number of goldfish Todd has.

Andrew has 10 more goldfish than Todd:

A = T + 10

Together they have 50 goldfish:

A + T = 50

Lets replace A = (T + 10) in the las equation:

T + 10 + T = 50

Lets solve T in this equation:

2T + 10 -10 = 50 -10

2T /2 = 40 /2

T = 20

Todd has 20 goldfish

Now lets calculate A = T + 10 = 20 + 10 = 30

Andrew has 30 goldfish
