To calculate:
Solve the system by the method of elimination. Label each line with its equation.
Answer to Problem 12E
There are infinite solutions for this pair of equations as they are consistent.
Explanation of Solution
Given information:
The given pair of equations are
Concept used:
These equations can be solved graphically and algebraically. We can use the method of elimination to solve it.
Calculation:
As per the given equations we can see that there are two variables and by adding these two equations we can eliminate one variable.
Before adding we need to multiply second equation with 3 so that we can cancel y variable.
By simplifying these equations we get,
Now let us add both the equations.
From this we can know that these two equations lie on the same line.
Conclusion:
There are infinite solutions for this pair of equations as they are consistent.
