### Exercise 2: Water Capacity

There are two water tanks, each with a capacity of 2450 liters. A total of 3500 liters of water has been used from both tanks. How much water is left in both tanks?

Solution:
The total water capacity in both tanks is:

2450 x 2 = 4900 liters

The remaining water in both tanks is:

4900 – 3500 = 1400 liters

Solve for x:

a) x : 5 = 1308
b) x : 6 = 1507

Solution:
a) x : 5 = 1308
x = 1308 x 5
x = 6540

b) x : 6 = 1507
x = 1507 x 6
x = 9042
