To solve the given equation.
Answer to Problem 9P
The solution is (-3, -1)
Explanation of Solution
Given information :
Given equations are,
Here we shall use the elimination method by making y coefficient same and then eliminating by adding both equations. We shall use elimination because it is easy to eliminate one variable just by adding the equations here.
Multiply second equation with 2 and then add both equations we get,
Now put
Hence the solution is (-3, -1)
