Math Problem Statement
Solution
The system of linear equations given in the image is:
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:
This new equation, , is clearly inconsistent with the original equation (2), which is .
Step 2: Interpret the result
Since multiplying equation (1) by 2 gives us , but equation (2) is , 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.
