Tank X has five times as much water as Tank W. If Eric adds 0.9 ℓ of water to Tank X and 2.3 ℓ of water to Tank W, both tanks will have the same volume of water. Find the volume of water in Tank X at first.

W |
X |
| Before |
1 u |
5 u |
| Change |
+ 2.3 |
+ 0.9 |
| After |
1 u + 2.3 |
5 u + 0.9 |
Both tanks have the same volume of water in the end.
5 u + 0.9 = 1 u + 2.3
5 u - 1 u = 2.3 - 0.9
4 u = 1.4
1 u = 1.4 ÷ 4 = 0.35
Volume of water in Tank X at first
= 5 u
= 5 x 0.35
= 1.75 ℓ
Answer(s): 1.75 ℓ
