Math Problem Statement

Determine the solution set of the system of linear equations by elimination. 6x - 5y = 0 and 12x - 10y = -3.

Solution

The system of linear equations given in the image is:

(1)  6x5y=0\text{(1)} \ \ 6x - 5y = 0 (2)  12x10y=3\text{(2)} \ \ 12x - 10y = -3

We are asked to solve this system by the method of elimination.

Step 1: Analyze and simplify the equations

Looking at the two equations, we can notice that equation (2) is just a multiple of equation (1). Specifically, equation (2) is twice equation (1), except for the constant term on the right-hand side.

If we multiply equation (1) by 2, we get: 2(6x5y)=2(0)2(6x - 5y) = 2(0) 12x10y=012x - 10y = 0

This new equation, 12x10y=012x - 10y = 0, is clearly inconsistent with the original equation (2), which is 12x10y=312x - 10y = -3.

Step 2: Interpret the result

Since multiplying equation (1) by 2 gives us 12x10y=012x - 10y = 0, but equation (2) is 12x10y=312x - 10y = -3, we see that there is a contradiction. This means that the system of equations has no solution. The lines represented by these equations are parallel and never intersect.

Conclusion:

The solution set for this system of linear equations is empty because there is no solution.
