540-120=420(т)- топлива ост

Answer 2

Calculating the Amount of Gasoline Delivered to the Station

To solve this problem, we can use a system of linear equations. Let's denote the amount of gasoline as G and the amount of diesel fuel as D. We are given the following information:

1. The total amount of gasoline and diesel fuel delivered to the station is 540 tons: G + D = 540. 2. When both gasoline and diesel fuel were sold in equal amounts, 120 tons of diesel fuel and 130 tons of gasoline remained: G - 130 = D - 120.

We can solve this system of equations to find the amount of gasoline delivered to the station.

Solution:

First, let's solve the equation G + D = 540 for D: D = 540 - G.

Now, substitute D = 540 - G into the second equation: G - 130 = (540 - G) - 120.

Solving for G: G - 130 = 540 - G - 120, 2G = 790, G = 395.

Answer:

So, the amount of gasoline delivered to the station is 395 tons.
