Answer:
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
Explanation:
Let a be the capacity of old tank and b be the capacity of new tank.
A company added a new oil tank that holds 350 barrels of oil more than its old oil tank.
So we have b - a = 350 ----------------------equation 1
Together they hold 3650 barrels of oil
a + b = 3650 ----------------------equation 2
equation 1 + equation 2
2b = 3650 + 350 = 4000
b = 2000 barrels.
Substituting in equation 1
2000 - a = 350
a = 1650 barrels.
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
