Given a system of linear equations in two variables.
The method of elimination employs the elimination of one variable from the system of equations. Thus, the first step is to determine the variable that is to be eliminated. Then, the equations are multiplied with different non-zero constants and added together in a way so that the targeted variable is eliminated. In some cases, a simple addition would eliminate the variable. But, in general scalar multiplication is needed as said earlier.
Calculation:
Multiply the first equation
Multiply the second equation
Perform the addition
Thus, it is found that:
Find the value of
Thus, it is found that:
Substitute
Thus, it is found that:
Thus, the solution of the system of equations
Conclusion:
The solution of the system of equations
