Andrew has 10 more goldfish than todd. together, they have 50. goldfish. how many goldfish does each boy have?

Todd has x amount of gold fish
Andrew has x + 10 amount of gold fish
They have 50 in all

x +(x+10) = 50

2x + 10 = 50

2x +10 (-10) = 50 (-10)

2x/2 = 40/2

x = 20

Todd has x amount of goldfish, so he has 20 goldfish
Andrew has (x + 10) amount of goldfish, so he has 30, because 20 + 10 = 30

hope this helps
