3x+2y=1030
y=-x+400
2y=-3x+1030
y=-3/2x+515
-x+400=-3/2x+515
x=230 y=170
It is the origin of a graph; where the x-axis and y-axis intercept .

Answer:
12,000 Litres
Step-by-step explanation:
The tank is rectangular with given dimensions.
<em>The quantity of oil is the volume of oil given by:</em>
Volume of Oil = length * width * height of oil (depth)
