(3, -5)
Step-by-step explanation:
hope it helps :)
300,000 because if a number is above 5, 50, 500, 5000, etc. then it rounds up instead of down.
The correct answer is the first option.
If you want to use elimination, you can sum the two equations for example, so that the x's simplify:



Plug this value for y in one of the equations to derive the value of x:

So, the solution is 
Answer:
Decimial: 0.47
Percent: 47%
Fraction: 47/100

Answer:
The system will be found to be inconsistent or dependent.
Step-by-step explanation:
The matrix A will have no inverse for two different reasons:
- The system is inconsistent
- The system is dependent
In the latter case, the Gauss-Jordan method will find a set of parametric equations for a solution. In the former case, there is no solution.
The outcome will depend on the reason why there is no inverse.
