Answer by algebrahouse.com(1659) About Me  (Show Source):
You can put this solution on YOUR website!
x = amount in one container
2x = amount in other container {one container holds 2 times as much as the other}

x + 2x = 30 {the total amount of water is 30 gallons}
3x = 30 {combined like terms}
x = 10 {divided each side by 3}
2x = 20 {substituted 10, in for x, into 2x}

one container holds 10 gallons
the other container holds 20 gallons
