The problem is to solve the following system of linear equations:
We need to determine if there is a unique solution, infinitely many solutions, or no solution. If there is a unique solution, we need to find the ordered pair .
2. Solution Steps
We can use the method of substitution or elimination to solve the system of equations. Let's use elimination.
Multiply the first equation by 5 and the second equation by 2 to eliminate .
=>
=>
Subtract the second modified equation from the first modified equation:
Now substitute into the first equation :
So, the solution is and . The ordered pair is .
We can check the solution in the second equation:
. This is correct.
3. Final Answer
The solution to the system is .
