To calculate:The solution set for the system of equations with the help either substitution or elimination.

Answer to Problem 7MCQ
The solution set for the system of equations is
Explanation of Solution
Given information:
The system of equations
Calculation:
Consider the system of equations
Use the method of elimination to solve the system above.
Multiply first equation by
Add both the equations,
Therefore,
Now substitute
Therefore, solution is the coordinate pair,
Thus, the solution set for the system of equations is
