weight of car A is 15 lb less than the weight of two B cars. The truck weighs 2155 lb more than car A. What is the curb weight of each vehicle?

To find the curb weight of each vehicle, we can create a system of equations based on the given information.

Let's assign variables to the unknowns:
Let the weight of car B be x lb.
The weight of car A will be 15 lb less than twice the weight of car B, so it can be expressed as 2x - 15 lb.
The weight of the truck will be 2155 lb more than car A, which is (2x - 15) + 2155 lb.

Now, we can set up the equations:

1. Car A's weight = 2 * Car B's weight - 15 lb
A = 2x - 15 (equation 1)

2. Truck's weight = Car A's weight + 2155 lb
T = A + 2155 (equation 2)

To find the values of A, B, and T, we need to solve this system of equations simultaneously. Let's substitute equation 1 into equation 2 to eliminate A:

T = (2x - 15) + 2155
T = 2x + 2140 (equation 3)

Now we have two equations:

1. A = 2x - 15
2. T = 2x + 2140

Since we only need to find the curb weight of each vehicle, we have to solve for A, B, and T.

To find A, we can substitute the value of A from equation 1 into equation 2:
(2x - 15) = 2x + 2140

Simplifying the equation:
2x - 15 = 2x + 2140
-15 = 2140

This equation is not possible, which means there is no solution that satisfies the given conditions.

Therefore, we cannot determine the weights of car A, car B, and the truck with the given information.
