The given system of equation need to solve by using the elimination method:
Answer to Problem 12E
The solutions of set of eqns.
Explanation of Solution
Given:
Concept Used:
You have to use either addition or subtraction to find the value of one variable and then use this value of one variable to get value of another variable in the elimination method.
Calculations:
The given eqns. are:
Multiply by
Take the subtraction of eqns. (3) and (2):
Now, to find the value of
So, the solutions of given set of eqns. is
Conclusion:
Hence, the solutions of given set of eqns. is:
