Shirley has two containers of water for a camping trip. One container holds 2 times as much as the other. The total amount of water is 30 gallons. How much water is in each container?
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  Algebra House Comments are closed.
